Abstract: This study aimed to create a Learning Module in Purposive Communication course using the process Analysis, Design, Development, Implementation, and Evaluation or ADDIE instructional model design and looked into its acceptability based on the criteria on content, presentation or physical aspect, and instructional design. Analysis was the first step in the creation of the module in which the evaluation of the context was made. This was done through the analysis of the CMO 20, s. 2013, analysis of learners, teachers/faculty, learning condition, existing instructional strategies, and Purposive Communication course content. In the data gathering, a survey-questionnaire adapted from Munby’s Communication Needs Processor was utilized. The Design then emerged after a thorough analysis of the result and it was ICARE Design and it was used as the framework of the module. Data from the Analysis and Design phase was content analyzed and the result led to the development of the module in the Development phase. The module was then validated though the use of researcher-made instructional material evaluation instrument fully validated by experts. Implementation phase was done through the Pretest-tryout-Post-test sequence. Evaluation phase then followed. The output of the module was evaluated in terms of process and product. Process evaluation result showed a higher mean score in the Post-test after exposing the students to the module. Moreover, module validation resulted to a Very Acceptable rating from the Jurors. In addition, modular instruction was perceived advantageous and helpful by students and teachers, as revealed by the thematic analysis of their perception on this method of instruction. Product evaluation, on its part, showed a General Acceptability of the module according to the teacher/user with regard to the use of the product.

Abstract: The mission statement is to design a cost-effective, scalable and portable MEMS based control system for the physically handicapped with high accuracy and programmability. The project focuses on head movement recognition via displacement in different directions. Many approaches have been made using cameras and computer vision to interpret sign language. Gesture recognition is a way for machines to begin to understand human body language, thus building a richer bridge between human and machines. Approximately 6 million people in the world face the problem of disability due to paralysis of various degrees. The proposed work is to provide a system that can be used by physically challenged people to control various devices using head movement. The system comprises of a microcontroller employing a MEMS accelerometer senses displacement signals. The direction along x- axis, y- axis, z- axis is real time detected by the software which in turn communicates to the various devices to function accordingly.

Keywords: Head movement recognition, Gesture recognition, MEMS accelerometer.

Abstract: The fouling organisms cause effective problems in several strategies by settling on ships’ hulls, aquaculture systems, fishing nets, pipelines and other marine infrastructure. Ships suffer increased drag and surface corrosion, leading to lower speeds, thereby causing higher fuel consumption, additional CO2 emissions and maintenance costs, hence this current review focused on prevention of biofouling by several physical methods like membrane ultrafiltration by surface modifying macromolecules and reverse osmosis. Ultrasonification is also used widely as a physical treatment to prevent biofouling bacteria’s adhesion to the marine surfaces. Membrane ultra-filtration by silver nanoparticles (nAg) which are greatly known for antibacterial activity with polysulfone ultrafiltration membrane (nAg-psf) exhibits a wide antimicrobial resistance against several bacterias like Escherichia coli thereby reduced the potential of fouling. Tri-n-butyltin (TBT) is reasonably effective in controlling microbial fouling but it would affect marine life at both lower and higher concentrations. To replace this chemically modified antifouling agent, there is a wide need for the development of “eco-friendly” antifouling agent, so the most potential marine microbes like marine algae were identified, characterized by antimicrobial assay and several metabolites were purified by Thin layer chromatography and column chromatography and it’s been used as an effective antifoulants. The chemical structures of the metabolites were further assayed by spectral methods. Thus, our present review also presented the benefits associated with the use of different marine organisms, including marine bacteria, algae, sponge, coral, bryozoa, ascidian, etc. as source means that they are the organisms of choice for obtaining natural products for antifouling coatings.

Abstract: This paper presents a review of an Earned Value Management System (EVM) for assessing project performance compared to others methodology. This study attempts to solve problem to the project manager and project stake holder in handling complicated, dynamic and massive project information especially when changes to the project baseline which is unavoidable. Through feasibility review study, it has been shown that the EVM provide an objective measures of the work that project manager can access project achievement by converting the project data into manageable information clusters and in parallel promoting the earned value management method as an effective tool to monitor and control project constraints which are cost, timeline and scope.

Keywords: Earned Value Management.

Abstract: Experimental analysis of shell and tube heat exchanger (STHE) with helical baffles has been carried out. Also comparative study of STHE with segmental baffles numerically is calculated. The numerical result show that under the same mean bulk temperature, heat transfer co-efficient and mass flow rate of shell and tube heat exchanger with helical baffle is higher than the shell and tube heat exchanger with segmental baffle and pressure drop of shell and tube heat exchanger with helical baffle is lower than the shell and tube heat exchanger with segmental baffle that’s result decrease pumping and capital cost. So the STHE with helical baffles might be used to replace the STHE with segmental baffles in industrial application to save energy, reduce cost and prolong service life.

Keywords: Heat transfer co-efficient, pressure drop, shell-and- tube heat exchanger, helical baffles, and mass flow rate.
