The School Principal Role in Motivating Second Cycle Teachers In AI Ain City.
This study aims to identify the role of school principals in motivating teachers in the second cycle schools in Al Ain City, through answering the following research questions: To what extent do school principals in Al Ain City schools assume the role of teacher motivation from the viewpoint of second cycle teachers in Al Ain schools? And what are the teachers\u27 proposals for activating the role of school principals in teacher recommendations/suggestions? A mixed (quantitative - qualitative) approach was used, which adopted a questionnaire and open questions. The research sample included 258 teachers in 4 boy schools in the second cycle in Al Ain. The study revealed that the motivational practices of school principals in the moral, administrative and social aspects, ranged from average to weak while financial motivation was very weak. Moreover, teachers stressed the need for enhancing all forms of motivation through making motivation methods such as professional development programs for school principals, giving school principals more powers and independence, and good vocational and educational choice of school principals who are able to invest the potential of teachers and motivate them
Towards designing a high intelligibility rule based standard malay text-to-speech synthesis system
Although text-to-speech (TTS) technology has
gained some interest from amateur and professional
researchers in developing a Standard Malay (SM) text-
to- speech synthesizer, however, up to this day, there is
rarely any high intelligible TTS system which is freely
accessible to be implemented and introduced to the
community of SM speakers. Therefore, identification of
the core components required for the development of
SM TTS system especially in establishing the NLP
module should be carried out intensively. This paper
presents a rule-based text- to- speech synthesis system
for Standard Malay, named SMaTTS. An intelligible
and adequately natural sounding formant-based
speech synthesis system with a light and user-friendly
Graphical User Interface (GUI) was developed. Result
and suggestion for future improvements is discussed.
The available Malay TTS synthesizers, the algorithms
and speech engine in used, as well as their strong and
weak points for each of the system are discussed in this
paper. Assessment was made at all possible levels;
phoneme, word and sentence level. The overall
performance of the system is analyzed using
Categorical Estimation (CE) for a comprehensive
analysis. Result and suggestion for future
improvements is discussed
SCAFFOLDINGAND REINFORCEMENT: USING DIGITAL LOGBOOKS IN LEARNING VOCABULARY
Reinforcement and scaffolding are tested approaches to enhance learning achievements. Keeping a record of the learning process as well as the new learned words functions as scaffolding to help learners build a comprehensive vocabulary. Similarly, repetitive learning of new words reinforces permanent learning for long-term memory. Paper-based logbooks may prove to be good records of the learning process, but if learners use digital logbooks, the results may be even better. Digital logbooks with an extended page with hyperlinked information on word-knowledge may work both ways – as scaffolding to learning as well as reinforcement to the learning process. In the present paper the researcher has suggested for the development of a software called ‘Vocabulary log book,’ which combines the features of Microsoft Word, online dictionary and online grammar books, so that the information needed by learners of a foreign language to learn its lexicon is available on a single page. The researcher believes that such a page will help learners master the new words quickly and efficiently
SMaTTS: standard malay text to speech system
This paper presents a rule-based text- to- speech
(TTS) Synthesis System for Standard Malay, namely SMaTTS. The
proposed system using sinusoidal method and some pre- recorded
wave files in generating speech for the system. The use of phone
database significantly decreases the amount of computer memory
space used, thus making the system very light and embeddable. The
overall system was comprised of two phases the Natural Language
Processing (NLP) that consisted of the high-level processing of text
analysis, phonetic analysis, text normalization and morphophonemic
module. The module was designed specially for SM to overcome
few problems in defining the rules for SM orthography system before
it can be passed to the DSP module. The second phase is the Digital
Signal Processing (DSP) which operated on the low-level process of
the speech waveform generation. A developed an intelligible and
adequately natural sounding formant-based speech synthesis system
with a light and user-friendly Graphical User Interface (GUI) is
introduced. A Standard Malay Language (SM) phoneme set and an
inclusive set of phone database have been constructed carefully for
this phone-based speech synthesizer. By applying the generative
phonology, a comprehensive letter-to-sound (LTS) rules and a
pronunciation lexicon have been invented for SMaTTS. As for the
evaluation tests, a set of Diagnostic Rhyme Test (DRT) word list was
compiled and several experiments have been performed to evaluate
the quality of the synthesized speech by analyzing the Mean Opinion
Score (MOS) obtained. The overall performance of the system as
well as the room for improvements was thoroughly discussed
Synthesis, structural and optical properties of ZnO Nano-rods used in Solar Cells fabrication
Sudan has vast areas of fertile land, abundance of minerals, water, winds and sunshine, many types of these energies become a valid option. However, in this research, the focus shall only be concern-ing one type of renewable energy, which is solar energy. The conventional solar cells are mainly made up of doped silicon electrodes. Their major task is to convert visible light to electrical energy according to the photovoltaic (PV) conversion method. However the production of these crystalline silicon solar cells is very complicated and expensive. Therefore the aim of this research is to produce ZnO nano-rods with optimum characteristics that can be used in the construction of low-cost solar cells. Zinc Oxide (ZnO) nano-rods in powder form were synthesized using the hydrothermal method, which is a simple and inex-pensive method. The refinement of X-Ray diffraction (XRD) pattern was used to find and investigate the structural properties of the nano-rods. The morphology and size of the ZnO nano-rods were determined by a Transmission Electron Microscope (TEM), while the EDX studies confirmed the formation of ZnO functional group. The optical band gap energy was obtained using both UV-VIS-NIR diffuse reflectance and absortion spectroscopy also photo-luminesces (PL) was used
New Adaptive Data Transmission Scheme Over HF Radio
Acceptable Bit Error rate can be maintained by adapting some of the design parameters such as modulation, symbol rate, constellation size, and transmit power according to the channel state.<br />An estimate of HF propagation effects can be used to design an adaptive data transmission system over HF link. The proposed system combines the well known Automatic Link Establishment (ALE) together with variable rate transmission system. The standard ALE is modified to suite the required goal of selecting the best carrier frequency (channel) for a given transmission. This is based on measuring SINAD (Signal plus Noise plus Distortion to Noise plus Distortion), RSL (Received Signal Level), multipath phase distortion and BER (Bit Error Rate) for each channel in the frequency list. Channel condition evaluation is done by two arrangements. In the first an FFT analysis is used where a pilot signal is transmitted over the channel, while the data itself is used in the second arrangement. Passive channel assessment is used to avoid bad channels hence limiting the frequency pool size to be used in the point to point communication and the time required for scanning and linking. An exchange of channel information between the transmitting and receiving stations is considered to select the modulation scheme for transmission. Mainly MPSK and MFSK are considered with different levels giving different data rate according to the channel condition. The results of the computer simulation have shown that when transmitting at a fixed channel symbol rate of 1200 symbol/sec, the information rate ranges from 2400 bps using 4FSK up to 3600 bps using 8PSK for SNR ranges from 11dB up to 26dB.<br /
English digits speech recognition system based on hidden Markov Models
The field of Automatic Speech Recognition (ASR) is about 60 years old. There have been many interesting advances and developments since the invention of the first speech recognizer at Bell Labs in the early 1950' s. The development of ASR increased gradually until the
invention of Hidden Markov Models (HMM) in early 1970's. Researchers' contribution were to make use of ASR technology to what can be seen nowadays of various advancements in fields like multi-modal, multi-linguaVcross-lingual ASR using statistical techniques such as HMM, SVM, neural network, etc [1]

Alpha 1 Acid Glycoprotein as a Marker for Diagnosis of Early-Onset Neonatal Sepsis in Full-term Neonates
Background: Neonatal sepsis is defined as a clinical syndrome of bacteremia with systemic signs and symptoms of infection in the first 4 weeks of life. Alpha-1 acid glycoprotein is one of the lipocalin family and members of acutephase protein; it appears to function in modulating the activity of the immune system during the acute phase reaction. Objective: This study aimed to assess α-1AGP as a marker in the diagnosis of EOS.Patients and Methods: This study was a prospective case-control study conducted on full-term neonates up to 7 days of life, admitted to the neonatal intensive care unit of Zagazig University Hospitals. The studied neonates were divided into 3 groups first confirmed cases (20) of early-onset sepsis, confirmed clinically and with a positive blood culture. Second suspected cases (20), with clinical features of sepsis and non-specific lab markers. Third group control (20), are apparently healthy term newborns, delivered in the Zagazig University Hospital. Alpha-1 acid glycoprotein was measured for all neonates. Results: There was a statistically significant difference among the studied groups as regard alpha one acid glycoprotein. It is a good diagnostic marker detection of cases. Conclusion: Alpha-1-acid glycoprotein appeared to be a useful marker for the early detection and diagnosis of earlyonset neonatal sepsis
