In my humble opinion the credit crisis will be resolved and we as the commercial loan brokers that stuck it out will be in a strong positions when the secondary market returns. These cycles happen every 10 to 15 years. Compare what is happening right now to the saving and loans crisis. During that cycle 1009 institutions went out of business. 1009… Last week Silver State Bank went out, we’re now at 11. 11 vs. 1009…Also, The Mortgage Banker Association came out with a report last week regarding default rates on the CMBS market. Though the default rate went up from .30% to .48% we are still at 20 year lows! To me this means that the fundamental on the commercial side are still in place.How long will it take to work out? I don’t know. I’m hearing a year, maybe a year and half. However deals are still closing. They may not be as fat as they where a year ago, but if you dig deep enough you can still find doable, “closeable” loans. With that being said residential loan officers and brokers that are in the midst of diversifying their income by brokering commercial loans, don’t underestimate the transition.But don’t get intimidated. Commercial loans are not that complicated especially on deals under $3,000,000. The trick is to learn to be able to spot doable deals. Not only deals that will close, but also loans that you will have a competitive edge on. It’s all about finding the right “hair” on the deal.And don’t try to wing it. We get loan applications all the time from residential loan officers that haven’t taken the time to learn the intricacy of the business. What you can’t afford is wasting months on deals that aren’t doable from the start. Training, any type of training for commercial loans is essential if you really hope to succeed as a commercial loan broker in this market.Now is the time to bear down, not think about switching industries; in a year or two we’ll be in a position to rake it in and on comrades that left the industry will still be trying to figure out their new industry.

Science of Wave Energy Conversion Systems for Sensor Buoys Furthered by Business and University
Introduction
The ocean is in constant motion and the effects of sea states are enormous. Ocean energy has a profound impact on the development of storm systems; shipping safety and shipping routes; recreational boating, surfing and swimming; and fishing and other methods of obtaining seafood. Wind-driven currents on the ocean surface extrapolate down into the ocean depths. Data from Sensor Buoys can provide critical information regarding ocean properties such as: ocean color, sea height, temperature, currents, and pollution.Power Problem
Existing power systems for remote sensor buoys and other remote ocean platforms often include solar panels and batteries. These systems would benefit form major improvement or replacement. Problems include: poor performance in cold and/or dark latitudes, insufficient power to operate the latest electronic equipment, high maintenance costs, high replacement costs, loss due to theft and vandalism, and battery disposal. Power harvesting from ambient ocean wave energy is a natural option to augment or replace any of these electrical-power-providing systems.Research Participants
Engineering companies, R&D groups, and universities are working on solving the issues of powering sensor buoys. Collaboration among these organizations is beneficial because of the great number of scientific areas that the development of self-powered sensor buoys encompass: marine geology and geophysics, biology, atmospheric and ocean chemistry and physics, marine hydrodynamics, electrical generators, advanced controls and dynamics, data communication, data acquisition, motor control and power systems. Close proximity to an ocean or a bay can provide researchers with easy access to test their power systems.Ocean Wave Energy Harvesting Systems
Ocean wave energy harvesting systems designed for sensor buoys convert wave motion into electricity to allow operation under all weather conditions. These new systems will enable enhanced functionality, higher performance and continuous operation. Such systems generate and accumulate energy that can be used to indefinitely power remote buoys equipped with sensor arrays as well as electronics for processing and communications. These power sources can be integrated with buoy systems to minimize the size of batteries, or to eliminate the need for batteries if super-capacitors are used. The goal is to store accumulated energy and form a completely self-contained, persistent, energy source platform suitable for a variety of sensor payloads.Obviously there are many challenges. The systems need to provide automatic wave energy harvesting and work with both drifting and moored buoys. The systems need to function at a low acoustic noise level and provide stealthy acoustic and visual operation plus a wide band response to the wave period. The elimination of batteries is the ultimate goal along with enhanced functionality, higher performance and continuous operationResearch Sponsors
There are numerous organizations interested in this technology. Some of the organizations that have provided funding include: the Office of Naval Research, the Space and Naval Warfare Systems Command, and the Rhode Island Science and Technology Council. Some of the projects investigated include the development of a small spar buoy, a direct drive system and a resonant drive system.Small Spar Buoy
This project was to devise a means of energy harvesting for a small diameter buoy free floating on the ocean surface. The buoy would contain an antenna on the upper portion and electronics for remote communications and sensing. The design would ensure that the buoy produce enough energy so that more than 4 milliwatts of power would be available at an instance. The required battery storage capacity would be at least 60 joules. Energy storage could include the use of a rechargeable battery. New scientific research has greatly extended both design concepts and theoretical analyses typically proposed for such systems and performed detailed numerical modeling that featured a wave-to-wire model of the power generation system in ocean sea states.Direct Drive System
A Direct Drive System has been developed that employs small electric generators that are directly driven via a surface buoy’s wave-induced heave motion. This system provides power from the differential motion between the buoy float and a submerged resistant plate. This configuration provides reliable operation without the need for additional gearing and has the ability to harness electrical power in the 1 to 10 Watt range in small sea states (WMO Sea State 1: Calm). The buoy response in the Direct Drive System is designed to match a wide range of expected ocean wave spectra based on the deployment location. Direct Drive of the system with wave motion results in broad band response with high efficiency. Other benefits of this system include low acoustic noise and stealthy operation.Resonant Drive System
A Resonant Drive System has been developed that employs small electric generators that are resonantly driven via a surface buoy’s wave-induced heave motion. This system amplifies the generator’s armature motion at the peak period of the sea state (WMO Sea State 1: Calm). The buoy response in the Resonant Drive System is designed to match the expected ocean wave spectrum based on the deployment location. The benefits of the resonant system include enhanced functionality, higher performance and continuous operation. The buoy is completely sealed with no external moving parts.Scale Model Testing
Scale model testing of the Direct Drive and Resonant Drive Systems has been performed in a wave tank as well as at the mouth of Rhode Island’s Narragansett Bay. This small buoy sensor system generates and accumulates energy that can be used to indefinitely power remote buoys equipped with sensor arrays as well as electronics for processing and communications. This power source can be used to minimize the size of batteries or to eliminate the need for batteries if supercapacitors are used. The buoy system design is customized and scalable (1-250 W) and can be suited to moored or drifting applications.Furthering the Science
This technology has many government and commercial applications including:
• Recharging stations for unmanned underwater vehicles
• Replacement or augmentation for solar power
• Elimination of batteries
• Sonar listening stations
• Weather monitoring buoys
• Wave monitoring buoys
• Tsunami warning stations
• Port monitoring buoys.The goal of these scientific endeavors is to develop wave energy converters that can operate in all environmental conditions and augment or replace any of the currently used battery/solar power systems with efficient, low-cost, ambient ocean wave energy systems.
Two Tier Education System For Higher Technical Education in India
IntroductionWith ever increasing use of technology and the internet in India and ever growing demand and need for expanding the coverage of Higher Technical Education there is a wide scope of introducing technology in the way the Higher Technical Education is imparted in India. In today’s environment mostly the methods employed are labor intensive, limited to class room interaction, access to which is not available to students in the event of they missing out the classes due to certain reasons. In addition there are difficulties in explaining and demonstrating the complex subjects involving three dimensional figures/models. More over it is an accepted fact that it is difficult for the students to concentrate on a subject in a typical classroom environment for more than about 20 minutes. The best of students have often been found to be losing concentration after about 20 minutes of classroom teaching which mostly becomes monotonous in traditional class where teacher mostly resorts to one way transmission without initiating interactive discussion. Though interactive sessions offer little improvement but it is not always possible to initiate the interaction till the time the students have developed certain level of understanding of basic concepts and fully understand the prerequisite required for a typical course.BackgroundIn order to improve teaching learning process it is important that we go beyond the boundaries of classroom and fixed timetable limits. The teaching material must be delivered to the student at a time, pace and place which provides best learning environment for him. This may have lot of variation depending on individual students needs. The EDUSAT program launched at the initiative of the government has also not achieved the desired success though large numbers of terminals have been established all over India and best of Professors are delivering lectures in real time environment. The root cause of failure can be attributed to the fact that it is still not getting out of a typical class room environment. Though virtual classrooms have been created but still it is limited to formalities of a classroom.Use of technology in improving the teaching learning process normally termed as Educational Technology – also known variously as e-learning, instructional technology and learning technology – is the use of technology to support the enhancement of learning process. It impacts upon the learning process, e.g. in delivering learning materials, facilitating communication and providing assessment and feedback. This technology can effectively be used to enhance and supplement the classroom teaching wherein the material is once again made available to the student at a time, pace and place that is best suitable for his needs. It will fill in the blanks which he must have drawn while he was in the classroom and could not clarify his concepts due to certain reasons. More ever certain other things like tutorials, tests, assignments etc can also handled effectively on line thereby saving the valuable time of the competent faculty members which can be used for other more useful activities.Course management systems (CMSs), which are online systems, were designed and developed to support classroom learning in academic settings, such as universities and other Educational Institutes. CMSs provide instructors with the ability to perform the following tasks:• Place course materials online. Most CMSs provide pre-programmed buttons for the course syllabus, course schedule, and course materials linked to specific lessons, such as copies of readings and PowerPoint slides from lectures.• Track student progress through assessment features, which enable instructors to give quizzes and tests online, and an online grade book, where instructors can post student grades.• Discussion board, where instructors and students can discuss readings and continue class discussions between formal class sessions.• Other communications tools, which let instructors send announcements to classes and communicate individually with students.• Lock box for students, where students can store class materials in a safe place-either a presentation to give later in class or backing up class assignments in a safe place.• Course statistics, which provide information on the use of the course site, including who used the course site and when.• Examples of CMSs include the commercial products Blackboard and WebCT, and the open source system like Moodle.MotivationWith ever increasing need for automation in the education system and the Government having decided to go for decentralization in Higher Technical Education in a big way there has been mushrooming growth of Engineering Institutions all over India. Good faculty members with thorough understanding of basic through advanced topics are difficult to find. With the current system of the faculty resources being utilized only for the benefit of the students enrolled with the Institute/University employing the concerned faculty, the scarce resources are not being utilized optimally. With the current developments and availability of Information Technology tools it may be possible to share the rich experiences of the distinguished faculty resources of certain key institutions in a typical University by other inexperienced faculty members of the same university engaged in teaching similar or same subjects.The basic idea will be to introduce two tier system in the higher technical education. The first tier will involve a continuous and consistent effort made to train and educate the fresh and inexperienced faculty members by using real time interaction with a group of experienced faculty members located at a center of excellence. This will involve creation of a “Nodal Center of Excellence” for each of the course being offered by the university. Such nodal center will design and develop a course by using the best suitable and simple to operate tools available in course management systems to perfection. This course will compulsorily be subscribed to by all faculty members engaged in teaching same course all throughout the University. They can share the expertise available at the nodal center and also clarify the intricacies of the subjects on a day to day basis as the course advances in the semester.The second tier of the system will involve Individual teachers who are already subscribed to the first tier discussed above. Such teachers will run their own course management systems for the benefit of the students attending their lectures.In this manner all the center of excellence established everywhere can be shared by all the institutes affiliated to the university and also the university campus colleges. This will result in:-• Uniformity in the coverage of the syllabus and its standardization.• Discovering the shortcoming of the syllabus and a common platform for discussing the same for future revision.• Clarification of the basic through advanced concepts through the chatting/tools offered by concerned selected service of the CMS.• Standardization and sharing of the grading and assessment of the students without significant variation form teacher to teacher.• Moderation of the grading centrally.• Readily available standardized course material which can be developed by networking of teachers sharing same subject in the university but at different institutions.• Standardization of reference books and the topics to be covered.• Standardization of the depth of individual topics to be covered for each subject.• Typical standardization of question bank.• Development of reference standard study material at the center of excellence which can be shared by all other institutions.• Automation of tutorial submission, FAQ answers, question paper generation, and response to earlier similar question asked.• Provision of authenticated links to related and useful material for further higher study for research.The System can be Implemented in these steps:Conceive, design and develop a two tier education system based on nodal concept of center of excellence in Engineering Education (Higher technical education) typical to Indian Universities by selecting the best suitable tools offered by Course Management Systems (CMS) available and demonstrate the viability of the concept.(1) Step one:(a) Identify the essential and desirable features which should be offered by the nodal center of excellence, in typical Indian University environment, to make it effective in sharing and updating its resources.(b) Carry out comparative study of the available course management systems world wide and selecting the best suitable system for this purpose.(2) Step Two: Developing a comprehensive module in selected course which should preferably support following features:-(a) Learning Tools• Book marking• Student Area• Library and Information Access• Annotation• Glossary• Course Index/Search Engine• Learning Exemplars/Guidance• Access to Grades• Student Guide• Self-Assessment Exercises• Study Skill Building• Student Web Pages(b) Collaboration Tools• Discussion Options• File Sharing• Work Group Areas(c)Faculty Tools• Course Planning, Design, Templates• Automated Glossary• Automated Course TOC/Index/Search Engine• File Management• Instructor Guide/Course Exemplars• Web Search Tools• Multimedia Capability(d)Course Management• Course Pages• Student Management• Automatic student assignment reminders (currently none of the CMS offer this currently)• Course Archive/Backup/Replication• Course Revision• Online Help/FAQs• Administration Tools• Automated Registration• Security• Student Transcript(3) Step Three: Implementing the nodal concept of center of excellence in real time and initiate the process for demonstration purposes.Milestones completedNodal concept has widely been applied in service, telecommunication and repair & maintenance industry wherein certain nodal centers are created with all the facilities and expertise available at easily accessible place which can be accessed by the prospective customers. In telecommunications wherein certain communication nodes are created and users can hook on to these nodes for getting the desired services. In education system the concept has widely been applied in various admission management systems and placement services.The concept of creating the Nodal center of excellence has been experimented in India by EDUSAT which is based on real time lectures in virtual classroom environment. However it has not invoked much enthusiasm. The root cause for this can be attributed to the fact that the lecture tends to be monologue and is not at a place, pace and time as may be required by the perspective learner. More over it lacks personal contact between the teacher and the students. The proposed two tier system of education involving nodal concept is intended to supplement the classroom teaching. It will be designed to optimize the contact time between the teacher and students in a way that the most important tings are attended to during the contact period and things of lesser importance can be attended to by the course management system like tutorials, class tests, assignments etc.This concept can be related to the service industry where in a nodal point, which can be termed as centre of excellence, is established which caters to the training needs of service engineers who are placed all over the operational areas. These service engineers in turn provide service to the customers. In case they find they are not able to address the problem they consult the nodal point for further advice. Almost same concept is applied in case of maintenance support provided by most of the companies for maintenance cover provided to their customers.The defense forces are known to have been using multi tier system for their training, maintenance and repair needs, though their system is not automated but the nodal concept is well established. In the proposed system we intend to use the two tier system with automation by using Course Management Systems.
