Title : Web-based Sanitary Permit Module: A Government-Academe Project Plan
Authors : Jaime P. Pulumbarit

A sanitary permit is issued by the local health authority for an establishment to operate, be it food or not food establishment. With the responsibility of ensuring safety, the development of a Web-based Sanitary Permit Module helps the Sanitation Division of the City Government of Malolos, Bulacan in the processing of sanitary permit to establishments (food or not food) applying or holds existing business permit. The Sanitary Permit Module logs the history of visits of the sanitary inspector and records the behavior of an establishment, including sanitary violations. Gathered sanitary data was identified, and then presented to the City Health Office for validation and approval. The sanitation permit documents apply the necessary regulations from the Local Government Unit of the Sanitation Division focuses on the range of the needs of automating the issuance of sanitary permit to an establishment and covers the following processes such as revoking permit, monitoring sanitation and other processes under the City Health Office of the Local Government Unit of Malolos, Bulacan. The project, however, does not cover the issuance of requirements regarding the requisition of sanitation permit, health certificate and sanitation request form. Thus, the Sanitary Division received sanitary requests from the business permits section.

Title : Digitized Measuring Wheel for computing signal losses due to cable length
Authors : Bernardo A. Pangilinan

The device solves the problem of determining the location of amplifiers in a cable television network and a telephone network. The device has a wheel with sensor attach to it to send pulses to the microcontroller equivalent to a certain distance traveled by the wheel. The microcontroller also accepts the attenuation factor per unit length available in the coaxial cable specification to be multiplied by the distance covered by the wheel and result in accumulated attenuation or losses produced by the cable at that length this were all done through the microcontroller. Another important parameter which can be input through the keypad towards the microcontroller is the threshold value of attenuation wherein the signal is no longer usable and needs amplification this will create an audible alarm that identify the location of the amplifier. This device will be beneficial in planning of distribution design for cable television using coaxial cable. This is also use for estimating accumulated losses due to cable length for telephone network which still uses coax and data network that uses copper.

Title : Barangay Office Management System
Authors : Jaime P. Pulumbarit,Jane Kristine G. Suarez

A Barangay is considered as the smallest unit of the government in the Philippines. It performs the initial operations such as formation and employing of programs, activities, policies and other that involved the community. As the Philippines, population increases, the number of households in each barangay in the country increases. As a result, more and more people are seeking the service of the barangay council as the unit of local government close to people. An increasing number of people mean increasing works for the barangay council members and staff. Today, population continually upgrades those results into a growing number of labor especially the Barangay Secretary, Barangay Treasurer, and Barangay Clerk. Summarizing the procedures in different barangay such as Barangay Tikay, Barangay Dakila, and Barangay Mojon in Malolos City, and Barangay Sta. Monica in Hagonoy, Barangay Panducot in Calumpit and Barangay Malhacan in Meycauayan requiring immediate response to this scenario a possible solution is an efficient and effective Management Information System. The development of a Barangay Office Management System enables the user to manage and print barangay citizen’s request and financial records and reports such as: Payroll for honoraria and allowance, Disbursement voucher, Account’s Advice, Purchase orders, Purchase Receipt, Reimbursement Expense Receipt, Inspection Report, Acceptance Report, Liquidation Report, Accomplishment Report, Requisition and Issue Slip, Summary of Cash Payments, Summary of Checks Issued, Summary of Paid Petty Cash Vouchers, Summary of Collections, Budget Information, Census, Barangay Cases, Barangay Certificates, Barangay Clearance, Barangay Indigency, Barangay Bonifide, Barangay Recommendation, Barangay Permits, Occupancy Permit, Building Permit, Business Permit, Billboard/Tarpaulin Permit and Excavation Permit. Regarding the development tools needed the researchers utilized PyDev Eclipse Version 2.2.4 for the Programming Language and MS SQL 2008 for the database.

Title : An inventory model for deteriorating items with variable type demand rate and different selling prices
Authors : P. R. Jayashree

Many goods undergo decay or deterioration over time which suffer from depletion by direct spoilage while stored. So decay or deterioration of these goods in stock is a very realistic feature and it is necessary to use this factor in inventory models. In this paper we have developed an order level inventory model for constant rate of deterioration. We have also considered a variable type of demand which behaves differently in the given time horizon. The demand rate is constant for a certain fixed time and then the demand varies linearly with time. This paper also deals with different selling prices in two different time periods. The objective of the model is to find the optimal on-hand inventory by considering the profit function.

Title : Reducing error rates in image transmission over 3g system using convolutional code techniques wireless communication networks
Authors : Udeh Ikemefuna James, Lois Onyejere Nwobodo, ,

Error correction codes are widely used in almost all digital systems as they provide a method for dealing with the unknown like noise. This research investigated the role of reducing error rates in image transmission over 3G systems using convolutional coding technique in MATLAB. The error correction code employed was the convolutional error correction codes. The performance of the codes are evaluated based on key performance indicators like Bit Error Rate (BER), number of symbols or data compared and number of errors detected. For the verification of proposed approach, computer simulation results are included. The results show a comparison of the performance terms of their Bit Error Rate (BER) of convolutional code with different code rate ( ½ and 1 /3 ) used. Based on the results, between 60% and 65% improvement on coding was achieved between reference points of 10-2 and 10-4 respectively for the two code rates. The results also show that as the Bit Error Rate (BER) decreased, the coded system can transmit data signals with at least 3dB less power, so making the performance of the coded system better than the uncoded system.

Title : Packet loss minimization in asynchronous transfer mode (atm) in wireless communication networks
Authors : Udeh Ikemefuna James,Lois Onyejere Nwobodo,

Asynchronous Transfer Mode (ATM) is a multiplexing/switching protocol for broadband services where information flow on logical connections are organized in fixed size cells called packets. The fundamental problem of this wide area switched networks is packet losses due to congestion, bit errors or deliberate discards/. This paper focused on the reduction of packet losses to ensure optimal performance of the ATM network. analysis of the distribution of consecutive cell losses in ATM switch and loss process analysis of the knockout switch using stochastic activity networks are proposed. UltraSAN, a SAN based performance modeling and analysis tool were used to automatically generate and construct the needed Markov processes of the underlying stochastic activities of the switch and workload. Packet losses and loss rate were determined using active probe utilities. Results showed that a percentage of 0.01 to 10 percent reduction in packet losses were achieved by the combination of high activity fractions and low loads.
