Oleh kerana itu, kajian melihat wujud keperluan agar Dasar Teknologi Hijau Negara dilihat kembali dalam konteks kepentingan pencapaian kepuasan pengguna berdasarkan ciri-ciri produk elektrik berteknologi hijau negara

Effect of the Alkyl Chain Length Incorporated into Donor Part on the Optoelectronic Properties of the Carbazole Based Dyes: Theoretical Study

In this paper, we report a theoretical study using density functional theory (DFT) and time-dependent (TD-DFT) for R-D-π-A systems with various alkyl chains (R). Results show that the LUMO of the dye lies above the semiconductor conduction band, promoting the injection of electrons; the lower HOMO level promotes dye regeneration. The incorporation of methyl chain (CH3) has a significant reduction in the gap energy, improved red-shift absorption spectrum and increase the molar extinction coefficient at the maximum absorption wavelength compared to D. While, the increase in alkyl chain length from C2H5 to C6H13 present a relatively reduce of gap energies, low effect on the wavelength (438 nm) and converged excitation energies.

Amazigh Spoken Digit Recognition using a Deep Learning Approach based on MFCC

The field of speech recognition has made human-machine voice interaction more convenient. Recognizing spoken digits is particularly useful for communication that involves numbers, such as providing a registration code, cellphone number, score, or account number. This article discusses our experience with Amazigh\u27s Automatic Speech Recognition (ASR) using a deep learning- based approach. Our method involves using a convolutional neural network (CNN) with Mel-Frequency Cepstral Coefficients (MFCC) to analyze audio samples and generate spectrograms. We gathered a database of numerals from zero to nine spoken by 42 native Amazigh speakers, consisting of men and women between the ages of 20 and 40, to recognize Amazigh numerals. Our experimental results demonstrate that spoken digits in Amazigh can be recognized with an accuracy of 91.75%, 93% precision, and 92% recall. The preliminary outcomes we have achieved show great satisfaction when compared to the size of the training database. This motivates us to further enhance the system\u27s performance in order to attain a higher rate of recognition. Our findings align with those reported in the existing literature

Assessing the Performance of a Speech Recognition System Embedded in Low-Cost Devices

The main purpose of this research is to investigate how an Amazigh speech recognition system can be integrated into a low-cost minicomputer, specifically the Raspberry Pi, in order to improve the system\u27s automatic speech recognition capabilities. The study focuses on optimizing system parameters to achieve a balance between performance and limited system resources. To achieve this, the system employs a combination of Hidden Markov Models (HMMs), Gaussian Mixture Models (GMMs), and Mel Frequency Spectral Coefficients (MFCCs) with a speaker-independent approach. The system has been developed to recognize 20 Amazigh words, comprising of 10 commands and the first ten Amazigh digits. The results indicate that the recognition rate achieved on the Raspberry Pi system is 89.16% using 3 HMMs, 16 GMMs, and 39 MFCC coefficients. These findings demonstrate that it is feasible to create effective embedded Amazigh speech recognition systems using a low-cost minicomputer such as the Raspberry Pi. Furthermore, Amazigh linguistic analysis has been implemented to ensure the accuracy of the designed embedded speech system

PERTIKAIAN POLISI DAN PERUNDANGAN TANAH DALAM CADANGAN PEMBANGUNAN TANAH: CONFLICT OF LAW AND POLICY IN LAND DEVELOPMENT

The processes involved in development are strongly tied to the land development policy and regulation. The Town and Country Planning Act 1976 [Act 172] and the National Land Code [Act 828] are among the laws regulating these processes. Cases such as Subang Jaya Municipal Council v. Visamaya Sdn. Bhd & Anor is one of the cases on the conflict of land conditions in the National Land Code (now revised in 2020 with the number [Act 828]) ("KTN") with the land use zone contained in the Local Plan issued by the Local Authority (PBT). Its decision offers a valuable lesson in legal matters and land planning. This study intends to take a firm stance on the interaction between land-related legislation, such as TCPA [Act 172] and KTN. Studies are carried out using the most recent court rulings and legislative modifications, using a doctrinal approach as the primary methodology. The Town and Country Planning Act of 1976 [Act 172] (often known as "Act 172") is the primary statute cited in project planning for development, according to the study. On the other hand, KTN, which went into effect on January 1, 1966, is the most significant land law in Peninsular Malaysia. The alleged legal inconsistencies must be clarified and justified, and this requires a thorough comprehension of the development of the relevant legislation's original process and original intent. The study finds that amendments to the laws or guidelines should be initiated to ensure the development process continues as planned.   Abstrak Pembangunan sesuatu kawasan berkait rapat dengan proses-proses berkaitan pembangunan tanah. Proses-proses ini dikawal oleh beberapa perundangan seperti Kanun Tanah Negara [Akta 828] dan Akta Perancangan Bandar dan Desa [Akta 172]. Kes Majlis Perbandaran Subang Jaya v Visamaya Sdn.Bhd & Anor mengenai konflik syarat nyata tanah dalam Kanun Tanah Negara 1965 (kini telah disemak semula pada tahun 2020 dengan nombor [Akta 828]) (“KTN”) dengan zon guna tanah yang terdapat dalam Rancangan Tempatan yang dikeluarkan oleh Pihak Berkuasa Tempatan (PBT) merupakan satu keputusan yang memberikan satu pengajaran besar dalam isu perundangan dan perancangan tanah. Kajian ini bertujuan untuk mendapatkan kedudukan sebenar berhubung kaitan antara akta-akta melibatkan pembangunan tanah seperti Akta Perancangan Bandar dan Desa 1976 [Akta 172] dan KTN. Kajian dijalankan melalui semakan kepada perundangan dan keputusan-keputusan mahkamah yang terkini serta menjurus kepada pendekatan doktrinal. Kajian mendapati bahawa Akta Perancangan Bandar dan Desa 1976 [Akta 172] (“Akta 172”) merupakan undang-undang utama yang dirujuk dalam suatu perancangan projek untuk sesuatu pembangunan. Manakala KTN pula undang-undang tanah terpenting yang digunakan di Semenanjung Malaysia yang berkuat kuasa pada 1 Januari 1966 berkaitan urusan tanah. Konflik perundangan yang dinyatakan perlu diperhalusi dan disokong dengan pemahaman yang mendalam berkaitan proses dan niat asal penggubalan perundangan berkaitan. Kajian ini mendapati cadangan pindaan atau penjelasan melalui garis panduan merupakan satu tindakan yang wajar bagi memastikan semua pembangunan dapat dijalankan tanpa menjejaskan polisi dan perundangan tanah sedia ada

KESEDIAAN DIRI ANGGOTA MASYARAKAT DARIPADA PERSPEKTIF PSIKOLOGI BERKAITAN BENCANA BANJIR DI DAERAH SEGAMAT

Peningkatan intensiti dan kekerapan bencana banjir kebelakangan ini di daerah Segamat menyebabkan kemusnahan harta benda dan kehilangan nyawa yang signifikan berkaitan dengan tahap kesediaan diri dalam kalangan masyarakat menghadapi bencana banjir. Objektif utama kajian adalah meneliti pengaruh diri masyarakat terhadap aspek kesediaan kognitif, afektif dan psikomotor dalam menghadapi bencana banjir. Seramai 1100 orang sampel masyarakat mewakili 11 mukim terlibat. Hasil kajian mendapati sebahagian besar mukim yang kerap dilanda banjir, menunjukkan hubungan signifikan dengan aspek kesediaan dari segi kognitif, afektif dan psikomotor. Kewujudan pelbagai tahap kesediaan ini bergantung kepada kekerapan kejadian bencana banjir yang berlaku di kawasan mereka. Perkara ini dibuktikan apabila mukim Chaah, Labis dan Pogoh yang tidak menunjukkan sebarang hubungan signifikan antara pemboleh ubah diri masyarakat dengan kesediaan dan menerima hipotesis null kerana kesemua mukim ini jarang dilanda banjir disebabkan topografi yang agak tinggi berbanding mukim lain di daerah Segamat. Hasil kajian ini penting kerana memberi impak terhadap keperluan penambahbaikan rangka kerja bersama dari aspek psikologi dalam Arahan 20 Majlis Keselamatan Negara sedia ada agar sistem pengurusan bencana banjir masa kini menjadi lebih baik

Kinetics and Isotherm Studies of Copper Removal by Brushite Calcium Phosphate: Linear and Non-Linear Regression Comparison

Abstract: Interactions of Cu(II) ions with calcium phosphate Brushite (DCPD) in aqueous solutions were investigated by batch conditions and under several sorption parameters like contact time, pH of solution and initial metal concentration. The retention of copper was found maximum and dominated by exchange reaction process in the pH range 4-6. The reaction process was found initially fast and more than 98% was removed at equilibrium. The kinetics data of batch interaction was analyzed with various kinetic models. It was found that the pseudo-first order model using the non-linear regression method predicted best the experimental data. Furthermore, the adsorption process was modeled by Langmuir isotherm and the removal capacity was 331.64 mg.g -1 . Consequently, Cu 2+ concentration independent kinetics and single surface layer sorption isotherm are then suggested as appropriate mechanisms for the whole process
