A Review on Microstrip Patch Antenna and its Miniaturization Techniques

— Microstrip patch antenna (MPA) has been widely in use since past three decades. The MPA consists of a metallic patch on the dielectric substrate over a metallic ground plane and is quite easy to design and fabricate. The minimum dimension of earlier MPA was half of wavelength which was very large for some communication devices; but recent some researchers have developed new standard for reducing the size of patch antenna. Many miniaturisation techniques have been introduced by researchers during recent years such as material loading, reshaping of antenna, shorting and folding, introducing slots and defects in the ground plane and the use of Meta materials. The major features and drawbacks of each of these approaches have been highlighted in this paper along their effects on antenna performance. This paper will provide better understanding for new researchers.

— Contrast Enhancement is very important for better visual perception and color reproduction. In this paper we explained the base enhancement techniques Histogram Equalization, Bi-histogram Equalization, Contrast Enhancement using Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD), Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD) and Contrast enhancement based on Dominant Brightness and Adaptive Transformation. The performance of every method is evaluated with parameters such Mean Square Error (MSE), Measure of Enhancement (EME), Peak Signal to Noise Ratio (PSNR) and Mean Absolute Error (MAE).
SFMM design in colocated CS‐MIMO radar for jamming and interference joint suppression

This study focuses on the problem of joint suppression of active jamming in target sector-of-interest (SOI) and out-of-sector interference for colocated compressive sensing multiple-input–multiple-output (CS-MIMO) radar. Three effective strategies for spatial filter measurement matrix (SFMM) design are outlined. Unlike the previous reported Capon beamformer and minimum variance distortionless response beamformer, the proposed design strategies only depend on the target spatial SOI rather than the accurate directions-of-arrival (DOAs) of targets, jammers and interfering sources to obtain deep nulls or notches for the SOI jamming and low-attenuation levels for the out-of-sector interference. The SFMM design criteria are derived using the second-order cone programming and solved as convex optimisation problems. The proposed approaches can simultaneously suppress the SOI jamming and attenuate the out-of-sector interference. Meanwhile, better DOA estimation accuracy can be achieved. Simulation results demonstrate the superiority of the proposed approaches over the other methods for colocated CS-MIMO radar.

Low-voltage aging-tolerant sram designs

The sub-threshold or near-threshold operation has been an attractive option for digital integrated circuit design due to the explosive growth of battery operated devices. This approach utilizes ultra-low/low supply voltage to decrease switching energy and suppressing leakage current to achieve low power operation. The effectiveness of power reduction makes it an excellent approach to prolong the battery lifetime and create an alternative opportunity for healthcare monitoring devices, which have limited power budget and low to medium signal processing capability. Static Random Access Memory (SRAM) is known as the critical building block in digital very large-scale integration (VLSI) circuit. It consumes large area overhead with high integration density in the modern System on Chip (SoC). This causes a large amount of leakage power contributed from SRAM array and is recognized as one of the bottlenecks in sub-100nm technologies. Therefore, application-specifically designed SRAMs for low power signal processing SoC have been popular and necessary. A column based split cell-VSS (CS-CVSS) data-aware write-assisted 9T SRAM with enhanced read sensing margin is developed. The CS-CVSS data-aware write assist improve both half-selected static noise margin and write margin while a 3T read port structure is applied for read sensing margin improvement. A 16kb 9T SRAM test chip with the proposed techniques is fabricated in 28-nm fully depleted silicon on insulator (FDSOI) technology and demonstrated VDD,MIN−Write = 470mV and VDD,MIN−Read = 250mV. Apart from suffering large leakage power consumption, SRAM reliability is another limiting factor in sub-100nm technology due to temporal variations. Temporal variations such as Bias Temperature Instability (BTI) and Hot Carrier Injection (HCI) shift the device threshold voltage (Vth) over its functional periods and eventually lead to soft or hard
Additive robotic fabrication of complex timber structures

The project described here, Additive Robotic Fabrication of Complex Timber Structures, investigates the potential and innovative methods for robot based assembly of complex wooden structures in the construction industry. Since 2012, in the framework of the National Research Programme "Resource Wood" (NRP 66)1, the ETH Zurich2 in cooperation with the Bern University of Applied Science3 has pursued the approach of industrially manufacturing non-standardized systems with digital fabrication. In that context material-specific and constructive aspects of wood assembly are combined in a continuous digital design and manufacturing process. In contrast to traditional approaches, for instance, mechanical processing of individual components and manual assembly, a robot based set-up as a further step in the pre-assembly is being investigated. This research approach is based on the assumption that efficient lightweight support structures can be manufactured from simple wood components of inferior quality or even from waste or left over materials. The first experiments with spatial wood assembly4 in connection with new types of adhesive and construction methods have been successfully carried out in several studies and with full scale prototypes.
FIR Filter Design Using Mixed Algorithm

— A method for the design of non recursive digital low pass FIR filter is proposed using GA. The main focus of the paper is to describe the developed and dynamic method of designing finite impulse response filter with automatic rapid and less error by an efficient genetic and neural approach. GA and Neural are powerful global optimization algorithm introduced in combinational optimization problems. Here, FIR filter is designed using Genetic, Neural approach by efficient coding schemes. The response is studied and implemented by keeping values of fixed order, crossover probability and mutation probability. Some data group of coefficients is used to train the neural network designed using generalized regression algorithm and rest are used as test input to neural network. GA & ANN offers a quick, simple and automatic method of designing low pass FIR filters that are very close to optimum in terms of magnitude response, frequency response and in terms of phase.
Offline Signature Verification based on Euclidean distance using Support Vector Machine

— In this project, a support vector machine is developed for identity verification of offline signature based on the matrices derived through Euclidean distance. A set of signature samples are collected from 35 different people. Each person gives his 15 different copies of signature and then these signature samples are scanned to have softcopy of them to train SVM. These scanned signature images are then subjected to a number of image enhancement operations like binarization, complementation, filtering, thinning, edge detection and rotation. On the basis of 15 original signature copies from each individual, Euclidean distance is calculated. And every tested image is compared with the range of Euclidean distance. The values from the ED are fed to the support vector machine which draws a hyper plane and classifies the signature into original or forged based on a particular feature value.
Effect of Fibers on Properties of Clay

- The use of natural fibers such as coir for soil improvement is highly attractive in countries like India where such materials are locally and economically obtainable, in view of the preservation of natural environment and cost effectiveness. This paper compares the effect of random inclusion of locally available coir fibers and commercial polypropylene fibers on compaction characteristics and California Bearing Ratio (CBR) values of soil. Standard Proctor tests and CBR tests are done on locally available cohesive soil (CH) with low percentage of reinforcement (0 – 1.5% by weight of oven-dried soil). The Maximum Dry Density (MDD) of fiber stabilized soil goes on decreasing and Optimum Moisture Content (OMC) goes on increasing with increase in percentage addition of coir and polypropylene fiber, irrespective of the percentage of addition of fiber. CBR test results reveal that the inclusion of randomly distributed fibers in soil increases the CBR values of the soil by two times. Coir fibers show very close percentile improvement in CBR value of soil when compared with polypropylene stabilized soil. Hence the inclusion of discrete coir fibers in random fashion significantly improves the CBR value of clay and hence could be effectively used for pavement sub-grade purposes.
Sakarya University Journal of Science SAUJS

We aimed to make censuses of Puffinus yelkouan at the Dardanelles and to evaluate the movements at the Aegean and the Marmara Sea during the early breeding period. Field studies were carried out in the morning and afternoon for 40 days between 6 February and 22 March 2019. In the censuses, the highest number of birds, passing in both directions in a day was 78145 individuals; 56451 of them were counted in the direction of the Aegean Sea on 17 February, which is the highest number counted in one direction in a day. As a result, the number of birds crossing to the Aegean Sea through the Dardanelles in the afternoon is significantly higher than the number of birds crossing to the Aegean Sea in the morning. In the afternoon, the number of birds flying towards the Aegean Sea is significantly higher than the number of birds flying towards the Marmara Sea. Considering that the species visits the breeding colonies at night, this movement pattern could be related to the fact that the shearwater breeding population is predominantly found in the Aegean or in the Mediterranean Sea. In addition, some issues, such as how long the birds stay in these sea regions after flying to the Aegean Sea or the Marmara Sea, which route they follow or how the flocks mix require further investigation.
Exploring Cultural Spaces Through Location-Based Mobile Games

This is an overview of game-related research of the HCI Group of the University of Patras. We are active in the area of location-based mobile games, with an interest at games that can enrich the cultural experience in open spaces (like city centres) and in museums aiming to actively engage citizens and/or visitors with cultural spaces. Over the past decade we have studied, designed, implemented and evaluated a number of games that run on mobile platforms (Windows PocketPC and Android). Our results include de-sign tools that can aid the design of such games (heuristic guidelines, design patterns, conceptual frameworks), game concepts and prototypes as well as implemented games.
Learned Legendre Predictor: Learning with Compressed Representations for Eﬃcient Online Multistep Prediction

We describe the Learned Legendre Predictor (LLP), a new algorithm for predicting function values at all points within a prediction horizon. The algorithm distinguishes itself from prior work in this area by making continuous time predictions, and by learning online. While we implement the algorithm using the Legendre polynomials as a basis, we derive the algorithm for the class of generalized Fourier coeﬃciens. For the purposes of demonstrating basic functionality we test the algorithm on predicting observations from the Mackey-Glass function and the Lissajous function. In this pure prediction setting we demonstrate performance comparable to oﬀ-line trained baseline algorithms trained on a comparable volume of data.
Kinesin-14 HSET may not oppose kinesin-5 Eg5 activity in RPE-1 cells

Human retinal pigment epithelium RPE-1 cells are immortalized diploid wild-type cells. RPE-1 is increasingly used for studies of spindle assembly dynamics and chromosome segregation. Here, we imaged living RPE-1 cells using the spinning disk confocal microscope and report their complete spindle assembly dynamic parameters. Live-cell experiments enabled ascribing precise timing of function of the kinesin-5 Eg5 and kinesin-14 HSET throughout different phases of mitosis. Eg5 functions at prophase and metaphase, to assemble and maintain spindle bipolarity, respectively. Eg5 inhibition results in spindle collapse during prophase and metaphase, resulting in monoastral/monopolar spindles. HSET functions throughout mitosis to maintain spindle length. HSET degradation results in shorter spindles through all phases of mitosis. Double-inhibition of Eg5 and HSET produces only monoastral/monopolar spindles, indicating that Eg5 and HSET may not be antagonistic in wild-type RPE-1 cells, contrary to previous studies using cancer cells. In the context of spindle assembly, our results highlight potential important differences between RPE-1 and other cancer-derived cell lines.
Evaluation of Effective Elastic Properties of Nitride NWs/Polymer Composite Materials Using Laser-Generated Surface Acoustic Waves

In this paper we demonstrate a high potential of transient grating method to study the behavior of surface acoustic waves in nanowires-based composite structures. The investigation of dispersion curves is done by adjusting the calculated dispersion curves to the experimental results. The wave propagation is simulated using the explicit integral and asymptotic representations for laser-generated surface acoustic waves in layered anisotropic waveguides. The analysis of the behavior permits to determine all elastic constants and effective elastic moduli of constituent materials, which is important both for technological applications of these materials and for basic scientific studies of their physical properties.

THE INDONESIAN JOURNAL OF BUSINESS ADMINISTRATION Vol. 2, No. 13, 2013:1605-1612 CRAFTING STRATEGY To IMPROVE XYZ RICE MILLING BUSINESS COMPETITIVENESS Ridho Herasmara and Mohammad Hamsal School of Business and Management Institut Teknologi Bandung, Indonesia ridho.harasmoro@sbm‐itb.ac. id Abstract— East Java rice milling business has been affected by a series of political policy regarding the industry, and increasing raw material purchase competition. This article is concerned about current competitive condition facing XYZ; it is experiencing problem of declining profitability even though the market is in uptrend. This decline is represented by problems in material purchase, production efficiency, and low selling price. The study and is aimed towards improving XYZ competitiveness and profitability. The literature review provided some generic framework in analyzing business condition and developing strategy (Wheelen & Hunger, 2012). Research is conducted by interviewing, observation of XYZ owner, and through secondary data gathering. Result of the research is analyzed to determine elements of business environment affecting XYZ. External analysis of the company point out strategic factors potentially important to the company such as market requirement of premium rice, differing price between east and west jave, as well as notable price discrepancy between area in East Java. Internal analysis of XYZ point out important strategic factors that affect XYZ in terms of its competitiveness, such as the relatively outdated production method and low direct sales effort of XYZ. From SWOT analysis of these factors, it is concluded that problem affecting XYZ competitiveness is requirement for reformulating business strategy. Based on it, a strategy is formulated for XYZ to improve competitiveness by upgrading production machinery, improve material purchase, and increase direct sales. It is concluded that the main problem of XYZ is low efficiency, and it is recommended that XYZ implement the solution to improve its competitive readiness and to prepare for future challenge.
A transmission line decoupling technique for enhancement of port isolation of dual-band MIMO antennas

Abstract In this paper, a transmission line decoupling network (TLDN) technique is presented to enhance the isolation of a dual-band multiple input and multiple output (MIMO) antenna. The MIMO antenna with enhanced isolation is designed by the following steps: Firstly, each port of an initial 2-port MIMO antenna is connected with an admittance transformer formed by two transmission line sections. The length and the width of the admittance transformer are designed to retrieve mutual admittance between ports having only imaginary part. The two ports are then connected in parallel electrically with the proposed TLDN to cancel the resultant imaginary mutual admittance. At the final stage, a simple dual-band matching network is added to each port to improve matching performance. The proposed method is applied to two designs of dual-band printed MIMO antenna working at 2.45 GHz/5.25 GHz and 1.8 GHz/3.5 GHz. For the purpose of verification, the two designs were fabricated and measured. The measured results are in good agreement with the simulation ones. Both designs yielded a high isolation, low envelop correlation coefficient, simple structures for design and fabrication. These features demonstrated the feasibility of the technique in implementing MIMO antennas.
Electronic Coupled Active Sidesticks in Dual Pilot Helicopters for Instructional Flights

Notably in training flights, mechanical linkages between pilot’s and copilot’s controls are crucial to the pilot’s situation awareness and to takeover control maneuvers. However, in near-obstacle helicopter scenarios, the control transfer between pilots can lead to loss-of-control accident caused by interaction on inceptors, as safety reports indicate. As an alternative to mechanical linkages, the electronic cross-cockpit control coupling is introduced as a smart flight control system to actively decouple inceptors, and thus to mitigate this category of accidents. The paper proposes a novel methodology to evaluate the suitability of the Electronic Coupled Active Sidesticks to helicopter domain, particularly applied to training flights. Results point to the ability of the electronic coupling to effectively emulate the mechanical linkage between control stations and perform full interventions on the linked mode. Moreover, test pilots rated the system capable to decouple controls either by priority override pushbutton (manual) or by priority algorithm based on the logics of pilot activities (automatic force threshold).
Edisi Khusus: Wet Lands Indonesia-Peat Lands DIVERSITY OF APHYLLOPHORALES FUNGI ISOLATED FROM TANJUNG PUTEVG NATIONAL PARK, CENTRAL KALIMANTAN AND ITS POTENTIALITY FOR LIGNIN DECOMPOSITION TypukArtiningsih,

ABSTARCT A total of fifty-three samples of fungal basidiocarp were collected from peat area in Tanjung Puting National Park, Central Kalimantan, Indonesia. These samples are mostly determined to genus until more studies are available. The fungi were isolated on CMA medium then the isolated strains were purified on PDA medium. The fungi belong to at least 3 families of Aphyllophorales, however there were a wide diversity in the genus with respect to macroscopic examination. An agar plate screening procedures was developed for the rapid selection of fungi and estimation of their capacity for lignin-decomposer. The test is based on the visualization and interpretation of the formation of halo zone or decolourization process in well-defined agar medium containing Poly R-478. The selected isolates were also tested in to rhemazol brilliant blue R salt (RBBR) medium. Five isolates had the ability to decolourize either Poly R-478 or RBBR. These isolates showed a qualitative lignin decomposition although a comparative study of selected fungi revealed the difference potentiality. The highest loss of lignin was 28.18% and attempts have been made to determine the unidentified fungi, which is resupinate type, by direct sequencing of 18s ribosomal DNA (rDNA).

OGLE-2017-BLG-1038: A Possible Brown-dwarf Binary Revealed by Spitzer Microlensing Parallax

We report the analysis of microlensing event OGLE-2017-BLG-1038, observed by the Optical Gravitational Lensing Experiment, Korean Microlensing Telescope Network, and Spitzer telescopes. The event is caused by a giant source star in the Galactic Bulge passing over a large resonant binary-lens caustic. The availability of space-based data allows the full set of physical parameters to be calculated. However, there exists an eightfold degeneracy in the parallax measurement. The four best solutions correspond to very-low-mass binaries near ( M1=170−50+40MJ and M2=110−30+20MJ ), or well below ( M1=22.5−0.4+0.7MJ and M2=13.3−0.3+0.4MJ ) the boundary between stars and brown dwarfs. A conventional analysis, with scaled uncertainties for Spitzer data, implies a very-low-mass brown-dwarf binary lens at a distance of 2 kpc. Compensating for systematic Spitzer errors using a Gaussian process model suggests that a higher mass M-dwarf binary at 6 kpc is equally likely. A Bayesian comparison based on a galactic model favors the larger-mass solutions. We demonstrate how this degeneracy can be resolved within the next 10 years through infrared adaptive-optics imaging with a 40 m class telescope.
