The customer preferences towards real estate property: The contributing factors / Muhammad Amir Asyraf Zulkefli

The title of this research is "The Customer Preferences Towards Real Estate Property: The Contributing Factors". The first purpose of this research is to determine the level of the customer preferences towards real estate property among the workers is Kulim Technology Park Corporation Sdn. Bhd. The second purpose is to determine the relationship between the factors of location, design, price and information towards the customer preferences towards real estate property. There are four independent variables involved which are Location, Design, Price and Information. Furthermore, the hypothesis was been constructed and focused on the objective to determine whether there has significant relationship between those independent variables with the customer preferences towards real estate property. A total of 150 respondents have participated. Besides that, the methodology for this research was primary data collection. For primary data researcher used questionnaire as primary data and all the information based on the questionnaire was analyzed and interpret. The reliability test, frequency analysis, descriptive analysis, Pearson's correlation coefficient testing and regression method was used for data analysis. Based on the multiple regression method, the results show that location, design, price and information are significant relationship to the customer preferences towards real estate property

Gradual color clustering elimination for outdoor image segmentation

One of the color reduction methods is color clustering, which has been applied for segmentation. Nonetheless, it has not been an appropriate method due to the automatically images change by luminance effects and color/texture variety. Hence, it can be done by improving the usual color clustering methods called customizing segmentation methods. This study focuses on customizing the color clustering methods for segmentation and object recognition in the outdoor images by utilizing a multi - phase procedure through a multi - resolution platform, based on self - organizing neural network, call ed gradual color Cluster Elimination (GCCE). The proposed method has been evaluated on outdoor images dataset namely BSDS and the results have been compared to PRI, NPR, and GCE statistical metrics of the latest segmentation methods which demonstrated that the proposed method has a satisfactory performance for the segmentation of the outdoor scenes

Peranti suis nanoelektromekanikal (NEM) berunsurkan grafin dan tiub nano karbon (CNT)

Suis nanoelektromekanikal (NEM) mempunyai persamaan dengan suis konvensional semikonduktor apabila digunakan sebagai transistor dan penderia walaupun prinsip operasinya berbeza. Perbezaan prinsip operasi suis ini memberikan kelebihan kepada suis NEM untuk beroperasi dalam persekitaran yang melampau manakala suis konvensional semikonduktor mempunyai kelebihan daripada segi infrastruktur fabrikasi yang canggih. Dalam kertas ini, kami mengulas kemajuan terbaru dan potensi teknologi NEM dalam aplikasi pensuisan berdasarkan bahan berasaskan karbon seperti CNT dan grafin. Kemajuan reka bentuk geometri suis NEM seperti struktur rusuk berlubang, mempunyai kelebihan daripada segi voltan operasi peranti yang rendah, turut dibincangkan dalam kertas ini. Berdasarkan Kitaran Gemburan Gartner, teknologi, proses dan produk untuk suis NEM atau hibrid NEM-CMOS berada di takuk berbeza iaitu di jurang ilusi, cerun pencerahan dan dataran tinggi produktiviti. Kemudian, reka bentuk geometri suis NEM berasaskan bahan-bahan ini diulas dengan lengkap berdasarkan kajian kepustakaan terbaru. Kami mengenal pasti cabaran yang terlibat dalam proses fabrikasi suis NEM berasaskan CNT dan grafin seperti kebocoran get dan proses litografi yang mencabar. Kesimpulannya, kami meringkaskan kertas kajian ini kepada beberapa sudut perspektif, pandangan dan peluang pada masa depan dalam teknologi suis NEM

Dual‐Gate Anti‐Ambipolar Transistor with Van der Waals ReS2/WSe2 Heterojunction for Reconfigurable Logic Operations

Abstract A dual‐gate anti‐ambipolar transistor (AAT) with a two‐dimensional ReS2 and WSe2 heterojunction is developed. The characteristic Λ‐shaped transfer curves yielded by the bottom‐gate voltage are effectively controlled by the top‐gate voltage. This feature is applied to logic operations, with the bottom‐ and top‐gate voltages acting as two input signals and the drain current (Id) monitored as an output signal. Importantly, a single dual‐gate AAT exhibits all the two‐input logic operations (AND, OR, XOR, NAND, NOR, and XNOR) under optimized input voltages. Additionally, drain voltage (Vd)‐induced switching between AND and OR logic operations is achieved. These features are advantageous for simplifying circuit design

Three-Dimensional Finite Element Method Simulation of Perforated Graphene Nano-Electro-Mechanical (NEM) Switches

The miniaturization trend leads to the development of a graphene based nanoelectromechanical (NEM) switch to fulfill the high demand in low power device applications. In this article, we highlight the finite element (FEM) simulation of the graphene-based NEM switches of fixed-fixed ends design with beam structures which are perforated and intact. Pull-in and pull-out characteristics are analyzed by using the FEM approach provided by IntelliSuite software, version 8.8.5.1. The FEM results are consistent with the published experimental data. This analysis shows the possibility of achieving a low pull-in voltage that is below 2 V for a ratio below 15:0.03:0.7 value for the graphene beam length, thickness, and air gap thickness, respectively. The introduction of perforation in the graphene beam-based NEM switch further achieved the pull-in voltage as low as 1.5 V for a 250 nm hole length, 100 nm distance between each hole, and 12-number of hole column. Then, a von Mises stress analysis is conducted to investigate the mechanical stability of the intact and perforated graphene-based NEM switch. This analysis shows that a longer and thinner graphene beam reduced the von Mises stress. The introduction of perforation concept further reduced the von Mises stress at the graphene beam end and the beam center by approximately ~20–35% and ~10–20%, respectively. These theoretical results, performed by FEM simulation, are expected to expedite improvements in the working parameter and dimension for low voltage and better mechanical stability operation of graphene-based NEM switch device fabrication
