RESEARCH OF PECULIARITIES OF ERROR DETECTION ON THE OUTPUTS OF PROGRAMMABLE LOGIC INTEGRATED CIRCUITS WITH FUNCTIONAL CONTROL BASED ON MODULAR CODES WITH SUMMATION

The article provides examples of the use of programmable logic integrated circuits in various industries. Possible faults in FPGA blocks and their difference from faults in programmable logic arrays are described. Particular attention is paid to the failures of the LUT element. Features of the organization of technical diagnostics systems operating in the operating mode of the objects of diagnostics for combinational logic devices, implemented on the basis of programmable logic integrated circuits are described. Using the example of modular summation codes, it is shown that the known approaches to organizing such systems for devices implemented on a valve basis can be directly applied to devices of the type under consideration. Since malfunctions in the form of errors are recorded, and not the malfunctions themselves, the approaches to the organization of diagnostic systems are universal. It also provides a comparative characteristic of modular sum codes depending on the code module. A code has been proposed that will detect all faults in the example under study.

Assessment of Food Security Status of Goat Farmers In Lagos State, Nigeria

The goat value chain plays a pivotal role in income and employment generation, livelihood enhancement; food and nutrition security among the poor, marginalized and disadvantaged groups and they are reared to supplement income and as a means of reducing food insecurity. The objective of this study is to assess the food security status of urban goat farmers in some local government areas of Lagos state, Nigeria. The use of qualitative method of data collection in the form of structured questionnaires were executed during the course of this study on a sample size of 80 goat farmers. Furthermore, during the course of the study, the specific objectives were analyzed using descriptive statistics as well as USDA food security code module. Using the Pearson’s rank correlation and binary logistic regression, the hypotheses were accurately tested to achieve results. From the result acquired, it was determined that men dominated women in the goat farming sector as well as revealing that the average age of respondents were 42.4 years. Furthermore, the results revealed that, about 65.4% of the respondents made an annual income ranging from 100,000-300,000 Naira and have been residents of the sample location for about 10-15 years. Another observation made from the results obtained during the course of this study showed that majority of the respondents practiced semi intensive system of management. This involves them using family labor (55.6%), having an average of 18.8 goats, as well as revealing sales as their main purpose of farming. More revelations from the result showed that, majority of the respondents were food insecure without hunger. Showing the major reasons for food insecurity to be insufficient finance, high cost of food and poor storage and processing. It was recommended that farmers be encouraged to belong to organizations such as cooperatives to solve problems in management and also for easy access or contact by government and extension agents.

Similarity Checking Similarity Checking of Source Code Module Using Running Karp Rabin Greedy String Tiling

Similarity checking of source code module, required a long process if it is done manually. Based on that problem, this research designed a software with structure-based approach using string matching technique with Running Karp-Rabin Greedy String Tiling (RKR-GST) Algorithm to check the similarity and using Dice Coefficient method to measure the level of similarity from 2 results source code modules. The result of the experiments show that RKRGST which applied in this system capable of recognizing the changing of statement and the changing statement order, and be able to recognize the syntax procedure testing that has been taken from its comparison module. Modification by adding the comment on source code module and changing of procedure name which is called in body of procedure can also be recognized by system. Processing time needed to produce output depends on the number of program code row that contained in source code module.

A Scaling Analysis for a General Passive Heat Removal System

Passive cooling technology has been adopted by more and more designs of advanced PWRs, because of its benefits to simplifying the design of safety systems, to reducing mis-operations performed by operators during accidents, and to cutting the cost of operation and maintenance. This paper presents a dimensional analysis by means of the Hierarchical two-tiered scaling (H2TS) method for the heat transfer process in a general passive heat removal system (PHRS) based on the research in which the most important phenomenon was conducted by a code module. The comparison of calculation results of the prototype and the experimental facility designed by the dimensional analysis shows that a scaled-down experimental facility could not simulate the flashing phenomenon which is the most important phenomenon in this process perfectly. But we could introduce a dimensionless parameter related to the flashing and choose an appropriate experiment condition to reproduction the flashing in the scaled-down facility. Our work in this paper made a well foundation for future design and experimental research of the PHRS.

REGENERATING CODETECHNIQUE IN DISTRIBUTED STORAGE

The Increasing need of storing large amounts of data presents a new challenge. One way to address this challenge is to use distributed data storage system. One of the strategies implemented in the distributed data storage system is using the technique of regenerating code. The code used in this technique is based on the algebraic structure of fields. Some studies have also been carried out to create code that is based on the other algebraic structure namely module. In this study, we attempted to assess the implementation of the code module at regenerating technique code. The study showed there is a potential properties code based on module that can be used in regenerating code technique. Keywords: Distributed storage, regenerating code technique, module code

Earth system modelling on system-level heterogeneous architectures: EMAC (version 2.42) on the Dynamical Exascale Entry Platform (DEEP)

We examine an alternative approach to heterogeneous cluster-computing in the many-core era for Earth system models, using the European Centre for Medium-Range Weather Forecasts Hamburg (ECHAM)/Modular Earth Submodel System (MESSy) Atmospheric Chemistry (EMAC) model as a pilot application on the Dynamical Exascale Entry Platform (DEEP). A set of autonomous coprocessors interconnected together, called Booster, complements a conventional HPC Cluster and increases its computing performance, offering extra flexibility to expose multiple levels of parallelism and achieve better scalability. The EMAC model atmospheric chemistry code (Module Efficiently Calculating the Chemistry of the Atmosphere (MECCA)) was taskified with an offload mechanism implemented using OmpSs directives. The model was ported to the MareNostrum 3 supercomputer to allow testing with Intel Xeon Phi accelerators on a production-size machine. The changes proposed in this paper are expected to contribute to the eventual adoption of Cluster–Booster division and Many Integrated Core (MIC) accelerated architectures in presently available implementations of Earth system models, towards exploiting the potential of a fully Exascale-capable platform.

Analysis On The Change In Neutronic Parameters Due To Mispositioning Of Fuel In The Ap1000 Core

<pre><span>AP1000 on the first cycle operation uses three types of UO₂ fuel enrichments that are 2.35 w/o, 3.40 w/o and 4.50 w/o. To compensate excess reactivity, AP1000 uses an Integrated Fuel Burnable Absorber (IFBA) and a PYREX absorber as additional compensator to the boric solution in the moderator. IFBA is a burnable absorber made from ZrB₂ which is integrated into the UO₂ fuel. Human errors, such as fuel misposition, could happen when operators load fuel assemblies into the reactor core. For evaluating the design performance of AP1000, analysis on the change of neutronic parameters due to this fuel mispositioning need to be done. Analysis was performed on the reactor at hot zero power condition (HZP), beginning of cycle (BOC), and zero xenon</span> <span>condition with several cases of mispositioning between two adjacent fuels. Neutronic parameters, mainly the k-eff and power factor distribution will be derived from SRAC2006 computer code module of CITATION. One of the inputs required is fuel lattice macroscopic cross-section data, which are generated by PIJ module. These calculations performed condensation energy group of 107 into 10 groups with JENDL - 3.3 library cross section data. </span><span>From the analysis, it can be concluded th</span><span>at misposition of the fuel in the first cycle of AP1000 core will result in very small change to the neutronic parameters. This very small change can not reduce the performance of the core.</span></pre>
