Authors: Suryanto Hendri , Sarip Sarip 
Published: May 2018

Getaran dari mesin (engine) adalah salah satu sumber getaran pada kendaraan. Getaran ini disebabkan adanya variasi tekanan gas di dalam silinder dan fluktuasi gaya karena gerakan berputar dan gerakan bolak-balik komponen-komponen mesin. Penelitian ini bertujuan untuk mengetahui besar getaran dan menganalisa getaran mesin empat langkah 550 cc dua silinder segaris, dengan memvariasikan sudut antar engkol 0o, 90o, dan 180o. Mesin ditumpu oleh tiga dudukan karet (rubber mounts) dengan posisi dua di depan dan satu di belakang. Penelitian dilakukan dengan membuat model dinamis mesin dalam lima derajat kebebasan. Gaya eksitasi yang bekerja pada mesin ditentukan dari tekanan gas hasil pembakaran dalam silinder dan gaya inersia bagian-bagian mesin yang berputar dan bergerak resiprokal. Input parameter-parameter lain dalam pemodelan ditentukan dari pengukuran bagian-bagian mesin yang terlibat dalam pemodelan, kemudian dilakukan simulasi model dengan software MATLAB Simulink untuk mengetahui respon getaran blok mesin dalam arah translasi vertikal (arah sumbu Y) pada variasi kecepatan putaran mesin 1000, 3000 dan 5000 rpm. Hasil simulasi menunjukkan getaran blok mesin terbesar terjadi pada posisi sudut antar engkol 180o dan terkecil pada sudut 0o.

IMAGE COMPRESSION USING MULTIRATE SAMPLING
Authors: Reddi D. Prathyusha , Giriprasad M. N. , Varadarajan Dr. S. 
Published: May 2018

This paper deals with a novel method of image compression. Â The proposed algorithm targets the psychovisual redundancy in the given image to improve compression. The properties or features of the image are initially modified (while ensuring that the image quality is not deteriorated) by down sampling along the horizontal and vertical dimensions. Â The transform is then applied on this modified image obtaining a better PSNR after compression than on the original image. Â The results obtained are compared with DCT and adaptive DCT. Also, the proposed algorithm is image independent as it gives consistently better compression performance for different images.
Language Fluency as a Factor in Machine Translation Comprehension
Authors: Aiken Milam , Park Mina , Lindblom Tobin 
Published: May 2018

Machine translations have been used for nearly 50 years, and although accuracy steadily improves, results do not often attain the standard set for human interpretation. Some people can understand poor translations better than others, but little is known about why this is so. Â Here, we show that language fluency was not a major factor in the ability of a human reader to comprehend a passage of text translated by computer, but prior topic knowledge could be.
Comparative Analysis of Simulation Time in Nonlinear and Harmonically Excited Pendulum and Duffing Oscillators
Authors: T. A.O. Salau , O.O. Ajide 
Published: May 2018

The motivation for the present study is derived from the fact that time mangaement is an integral part of good engineering practice. The present study investigated the quantification of the required computation time using two nonlinear and harmonically excited oscillators (Pendulum and Duffing) as case studies. Simulations with personal computer were effected for Runge-Kutta schemes (RK2, RK3, RK4, RK5, RK5M) and one blend (RKB) over thirty five thousand and ten excitation periods consisting the unsteady and steady solutions. The need for validation of the developed FORTRAN90 codes by comparing Poincare results with their conterpart from the literature informed the choice of simulation parameters. However, the simulation time was monitored at three lengths of excitation period (15000, 25000 and 35000) using the current time subroutine call command.
The validation PoincarÃ© results obtained for all the schemes including RKB compare well with the counterpart available in the literature for both Pendulum and Duffing. The actual computation time increases with increasing order of scheme, but suffered a decrease for the blended scheme. The diffencerence in computation time required between RK5 and RK5M is negligible for all studied cases. The actual computational time for Duffing (5-33seconds) remain consistently higher for corresponding Pendulum (3-23seconds) with difference (2-10seconds). Interestingly, the quantitative difference between the corresponding normalised computation time for systems and schemes is insignificant. It is insensitive to systems and schemes and formed a simple average ratio{ } for RK2, RK3, RK4, RK5, RK5M and RKB respectively. It is concluded that the end justified the means provided that computation accuracy is assured using the higher order scheme (with higher computational time ratio).
Mitigating the Distributed Denial of Service (DDoS) Attacks in Campus Local Area Network(CLAN)
Authors: Sen Angshu Maan , Singha K. Anand Kumar 
Published: May 2018

The Campus Local Area Network (CLAN) of academic institutions interconnect computers ranging from one hundred to about twenty five hundred and these computers are located in academic building(s), hostel building(s), faculty quarter(s), students amenities centre, etc all around the campus. The students, faculty and the supporting staff members use the network primarily for internet usage at both personal and professional levels and secondarily for usage of the available services and resources. Various web based services viz: Web Services, Mail Services, DNS, and FTP services are generally made available in the campus LAN. Apart from these services various intranet based services are also made available for the users of the LAN.
Campus LAN users from the hostels change very frequently and also sometime become targets (we call as soft targets) to the attackers or zombie because of either inadequate knowledge to protect their own computer/ laptop, which is also a legitimate node of the campus LAN; or their enthusiastic nature of experimentation. The interconnectivity of these legitimates nodes of the campus LAN and that of the attackers in the World Wide Web, make the computers connected in the LAN (nodes) an easy target for malicious users who attempt to exhaust the resources by launching Distributed Denial-of-Service (DDoS) attacks. In this paper we present a technique to mitigate the distributed denial of service attacks in campus wide LAN by limiting the bandwidth of the affected computers (soft targets) of the virtual LAN from a unified threat management (UTM) firewall. The technique is supported with help of bandwidth utilization report of the campus LAN with and without implementation of bandwidth limiting rule; obtained from the UTM network traffic analyzer. The graphical analyzer report on the utilization of the bandwidth with transmitting and receiving bits of the campus LAN after implementation of our bandwidth limiting rule is also given.

The Reliability of the Software Process can be monitored efficiently using Statistical Process Control (SPC). SPC is the application of statistical techniques to control a process. SPC is a studyÂ of the best ways of describing and analyzing the data andÂ then drawing conclusion or inferences based on available data. With the help of SPC the software development team can identify software failure process and find out actions to be taken which assures better software reliability. This paper provides a control mechanism based on the cumulative observations of Interval domain data using mean value function of Pareto type IV distribution, which is based on Non-Homogenous Poisson Process (NHPP). The unknown parameters of the model are estimated using maximum likelihood estimation approach. Besides it also presents an analysis of failure data sets at a particular point and compares Pareto Type II and Pareto Type IV models.
Performance Analysis of Planar Nanocavities-Based Wavelength Demultiplexer for Optical Communication Systems
Authors: Mahdi Rasha H. , Fyath Raad Sami 
Published: May 2018

This paper presents the design and analysis of planar plasmonic wavelength demultiplexer for optical communication systems. The demultiplexer is based on silver-air-silver plasmonic waveguide supported by two nanocavities for each drop channel. One cavity is used as a resonant tunneling-based channel drop filter while the other is used to realize wavelength-selective reflection feedback in the bus waveguide. Â For each channel, a parametric study is performed to characterize the performance of the two corresponding nanocavities when they are operating in isolated mode. Â The results are then used as a basis to design a single-channel demultiplexer by introducing the coupling between the two nanocavities. Simulation results are reported for a three-channel demultiplexer (1550, 1300, and 850 nm) using Computer Simulation Technology (CST) software package. A drop efficiency as high as Â is obtained for each drop channel in the designed demultiplexer. The simulated results can be used as a guideline to design ultra-compact wavelength-division multiplexing (WDM) systems in highly integrated optical circuits.Â

Published: May 2018

A wireless sensor network (WSN) consists of a large number of small sensors with limited energy. For many WSN applications, prolonged network lifetime is important requirements. There are different techniques have already been proposed to improve energy consumption rate such as clustering ,efficient routing , and data aggregation. In this paper, we present a novel technique usingÂ clustering .The different clustering algorithms also differ in their objectives. Sometimes ClusteringÂ suffers from more overlappingÂ and redundancy data since sensor node's position is inÂ a critical position does notÂ know in which clustering itÂ is belonging. One option is to assign these nodes to both clusters, which is equivalent to overlap of nodes and data redundancy occurs. This paper has proposed a new method to solve this problem and make use of the advantages of Support Vector Machine SVM to strengthen K-MEANS clustering algorithm and give usÂ more accurate dissection boundary for each classes .The new algorithm is called K-SVM.Numerical experiments are carried out using Matlab toÂ simulate sensor fields. Through comparing with classicalÂ K-MEANS clustering scheme we confirmedÂ thatÂ K-SVMÂ Â algorithmÂ has a better improvement in clustering accuracy in these networks.

Authors: Ghosalkar Samikshya Suresh , Ray K P , Rangari Rajesh G , Gharge Saylee Milind 
Published: May 2018

The paper mainly focuses on the beam forming and its analysis for planar phased- array antenna, which is being developed as part of the ST Radar. The beam steering is done electronically by controlling the phase of the T/R module in such a way that the phase difference between each module is equal and it corresponds to the steering angle. The relative phase shift of each T/R module for a specified beam position is worked out using MATLAB and implemented using 6- bit digital phase shifter. The analytical results are practically demonstrated using the STM32F4xx kit of STMicroelectronics. Theoretical values of the elemental phase for each antenna element in the array, are calculated for various positions of the beam (Î¸ & Ï†). The 6-bit phase shifter results in 5.6250 phase resolution.Â In the second part of the work, the calculation of the element phase with 6-bit digital phase shifter is discussed. The calculated values of the elemental phase are truncated to an integral multiple of 5.6250.Â
DEVELOPMENT OF AN INTRUSION DETECTION SYSTEM IN A COMPUTER NETWORK
Authors: R.S Babatunde , K.S Adewole , S.O Abdulsalam , R.M Isiaka 
Published: May 2018

The development of network technologies and application has promoted network attack both in number and severity.Â The last few years have seen a dramatic increase in the number of attacks, hence, intrusion detection has become the mainstream of information assurance. A computer network system should provide confidentiality, integrity and assurance against denial of service. While firewalls do provide some protection, they do not provide full protection.Â This is because not all access to the network occurs through the firewall.Â This is why firewalls need to be complemented by an intrusion detection system (IDS).An IDS does not usually take preventive measures when an attack is detected; it is a reactive rather than proactive agent. It plays the role of an informant rather than a police officer. In this research, an intrusion detection system that can be used to deny illegitimate access to some operations was developed. The IDS also controls the kind of operations performed by users (i.e. clients) on the network. However, unlike other methods, this requires no encryption or cryptographic processing on a per-packet basis. Instead, it scans the various messages sent on a network by the user. The system was developed using MicrosoftVisual Basic.

Published: May 2018

Antenna is paramount element for the radio communication entity using radio frequency and microwaves.Â In twenty-first century wireless communication systems, there is a demand for wider bandwidth, multiband and low profile antennas for both commercial and military purposes. This has initiated antenna analysis in various directions; one of them is using fractal shaped antenna elements. Fractal concepts have emerged and advanced as a unique technique for designing compact UWB antennas, because of the self-similarityand space-filling attributes. In a fractal antenna, the multiple frequencies of operation depend on the total dimensions of the design and the scale factor. There are varied fractal geometries that have been found to be favorable in developing novel and new models for antennas. In this paper we will be discussing one such type of fractal antennas i.e. the Koch structure.Â Koch antenna can be designed with a triangle, rectangle and pentagon as its initiator. Their geometry and parameters have been analyzed in this paper.Â
