XYZ in Surabaya is engaged in the production of commercial ships, providing ship repair and maintenance services as well as general engineering with specifications based on orders. Along with the development of the technology industry, ship production requires every shipyard to evaluate the system used. The time delay is the problem of building a 60 meter commercial ship. The Precedence Diagram Method (PDM) is a method for scheduling project time and showing critical trajectories of project activities. The results showed that in the project scheduling, there are 13 activities that have a zero value or critical activity which are activities Hull Fabrication, Hull Sub Assembly, Hull Assembly, Hull Erection, Blasting and Painting Raw Material, Finishing Hull, Anode, Machinery Outfitting, Cabling, Computing and Information, Machinery Commisioning, Equipment Commisioning, Harbour Acceptance Test, Yard Trial, Delivery to Customer So that it needs more strict control and supervision from the contractor in carrying out the activities of the 60 meter commercial ship building project activities for each activity/activity so that it does not experience delays and the project can be completed on time.","PeriodicalId":158702,"journal":{"name":"International Journal of Systems Applications, Engineering & Development","volume":"38-40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123637663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the image processing and human computer interface system application requires higher memory requirements, the power and area should be small. Searching of data is a high priority work in image classification. To perform high speed search through hardware Content Addressable Memory is used. But the circuit suffers from higher power consumption, precharging issues and low performance. For longer word length the elimination of precharge is needed. So for high speed applications self-controlled precharge-free CAM (SCPF-CAM) is suitable. A 4T hybrid self controlled pre charge free Content Addressable Memory is proposed in this paper using CMOS 32nm technology. The observation shows that the circuit works at high speed, minimizes the search time and has high performance operation. When compared to the conventional SCPF-CAM, 8T CAM the proposed design reduces the number of transistors. The reduction in area is about approximately 20% and can be used in low power and low energy applications. In Synopsis HSPICE Predictive technology models were used for the implementation in 32nm CMOS technology. The work will be extended in future using FinFET technology where the leakage current can be minimized.","PeriodicalId":158702,"journal":{"name":"International Journal of Systems Applications, Engineering & Development","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130996223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome the above challenges, FinFET has the advantages of an increase in the operating speed, reduced power consumption, decreased static leakage current is used to realize the majority of the applications by replacing MOSFET. By considering the attractive features of the FinFET, an ALU is designed as an application. In the digital processor, the arithmetic and logical operations are executed using the Arithmetic logic unit (ALU). In this paper, power efficient 8-bit ALU is designed with Full adder (FA) and multiplexers composed of Gate diffusion input (GDI) which gained designer's choice for digital combinational circuit realization at minimum power consumption. The design is simulated using Cadence virtuoso with 20nm technology.

Thus strengthening low cost CMOS digital design with Radiation Hardened by Design (RHBD) approach can be of paramount significance compared against the high cost Radiation Hard by Process (RHBP) approach. With this motivation, in this paper a novel and robust All-Digital-Phase Locked Loop (ADPLL) design has been developed for frequency synthesis. Our ADPLL design model encompasses multiple novelties and contributions including Feedback-Divider-Less-Counter (FDLC) based ADPLL, predictive phase-frequency detection (PFD), enhanced Time to Digital Converter (TDC) to detect next-edge occurrence of the reference clock that reduces locking period and complexity. The predictive PFD applies a phase-prediction scheme that delays the clock-edges of the reference frequency with a calibrated amount that it always aligned towards the expected frequency clock edge. It makes TDC to be narrow enough to cover the reference and oscillator jitter. Our proposed ADPLL design applied a narrow range converter (TDC) that assist phase-error prediction, correction and phase detection. The reference clock delay facilitates accurate timing relationship estimation with the variable frequency and hence performs retuning of the variable clock to reduce locking period and reduce noise. The ADPLL design has exhibited satisfactory performance for the frequency synthesis with reference frequency of 20MHz and the synthesis frequency of 2.4 GHz meeting radiation hardened features. The simulation results has revealed that the proposed Rad Hard ADPLL design can be a potential solution for space communication systems by maintaining low jitter of 340ps and power consumption of 371.7mW, as the narrow range TDC designed can detect sample radiation induced impulse noise of 20ns, 1mV and correct it.","PeriodicalId":158702,"journal":{"name":"International Journal of Systems Applications, Engineering & Development","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114989845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of the three-phase direct torque control shows that this concept can be extended easily to double star induction machine even when it is fed by a multilevel inverter. Diode-clamped inverter, as one of the prominent multilevel inverters, has several advantages like high voltage and low current waveform distortion. However, it suffers from the problem of neutral point potential variation. The variation causes an unbalance in the DC-link voltage levels and increases consequently the current waveform distortion. This problem can be solved in satisfactory way by using multilevel direct torque control equipped by a balancing strategy. The simulation results, illustrating the steady state and dynamic performances, prove the effectiveness of the proposed control approach.","PeriodicalId":158702,"journal":{"name":"International Journal of Systems Applications, Engineering & Development","volume":"216 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113984942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
