Energy analysis for food industries in Malaysia / Mohamed Bashir Ali Bashir
No full textThe industrial sector is the largest consumer of energy in Malaysia. Malaysian food industries consume a significant amount of energy, about 14% of total manufacturing energy consumption. Therefore, the recent increase in energy cost has created has an essential consequence for developing alternative energy efficient technologies. In this case, energy efficiency means reduction of environmental degradation, increase of sustainability and cost savings. This dissertation focuses on the energy savings, economic benefits and emission reductions. These objective could be achieved by installation of variable speed drives, high efficiency motors, waste heat recovery unit of the boiler, new efficiency lamp (T5) for lighting and repairing, purpose of critical equipment in Malaysian food industries. It has been estimated that the total amount of 1,428, 2,129 and 2,466 MWh energy savings can be achieved annually by utilizing high efficiency motors for 50%, 75% and 100% motor loads respectively. It was also found that for different motor loads, an estimated US136,252 and US$157,832 could be saved in anticipated energy costs and subsequently 843, 1,257 and 1,456 tons of CO2 emission reductions could be obtained at 50%, 75% and 100% motor loads respectively. It was also found that, the average of payback period associated with energy savings are about 2.01, 1.61 and 1.40 years for 50%, 75% and 100% motor loads respectively. Similarly, sizeable amount of energy can be saved using VSDs, waste heat recovery, new efficiency lamps (T5) and repairing leakages, resulting to curb energy costs. Furthermore, a considerable reduction in the amount of emissions can be obtained together with the associated energy savings for different energy savings strategies. In addition, the payback period for different energy savings strategies has been firmly established

Thermoelectric properties of LaCo4Sb12 skutterudite materials by addition of Al, In, Ni & Te / Mohamed Bashir Ali Bashir
No full textSkutterudite is a superior material used in thermoelectric application. In this work, the crystal structure and morphology of the ternary skutterudite (La/Yb)xCo4Sb12 were modified by incorporating of various addition such as Al, In, Ni and Te. This process was conducted via two step method namely mechanical alloying and spark plasma sintering technique. Specifically, the phase structure and morphology of the bulk samples were examined by X-ray diffraction (XRD) and scanning electron microscopy integrated energy-dispersive X-ray spectroscopy analysis (SEM-EDS), respectively. The thermoelectric properties of the bulk samples were measured in a temperature range of 300 K to 800 K. Furthermore, the oxidation and thermal properties of the samples were studied using a thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) that measured from 25 °C to 1000 °C. Evidently, it is proved that all of the samples demonstrated a dominant phase of polycrystalline CoSb3 skutterudite. Among the sample, Al0.05La0.5Co4Sb12 exhibited an excellent electrical properties, as manifested by its optimum carrier concentration and lowest electrical resistivity of 7.6μΩm at 314 K. In terms of the Seebeck coefficient, La0.5Co4Sb11.7Te0.3 recorded a highest value of 300 μV/K at 404 K. In the thermal conductivity behaviors, Al0.3La0.5Co4Sb12 sample showed the lowest thermal conductivity and lattice thermal conductivity values of 1.1 W/mK (314 K) and 0.64 W/mK (595 K), respectively. This occurrence can be related to the enhancement in phonon scattering by rattling Al atom into the lattice cages. Al0.05La0.5Co4Sb12 also presented a highest dimensionless figure of merit (ZT) which is 1.36 at 789 K, validating the substantial mitigation in electrical resistivity and lattice thermal conductivity. In conclusion, it has been proven that the modified materials possess notable oxidation and thermal stability in high temperature regime up to 800 °C
Cellular communications using aerial platforms
No full textA cellular communications network based on aerial platforms (APs) is addressed. Each AP is located in the stratosphere and carries an adaptive antenna array whose multiple beams are able to create a carpet of contiguous cells of different sizes on the earth's surface. Under ground station control, these cells can be rapidly moved to match the network resources to the varying teletraffic load created by roaming mobile users. After reviewing the basic principles of multiple beam adaptive antenna arrays, we focus on a single AP and derive the basic system parameters; such as the area covered by an AP, the equations governing the cells formed by the beams on the earth, the signal-to-interference ratio (SIR) calculations, the size of the antenna array required to form cells of a specific size, the requisite transmitted power, and so forth.Next, an in-depth analysis of the performance of an AP system using CDMA technology is performed for both the up-links and the down-links assuming free-space propagation. The performance is evaluated in terms of bit error rate (BER) and outage probability p0. We show that the system can support up to 24 users per channel with p0 < 10-3 if the required BER < 10-3 and the processing gain is 511.An analysis of the effect of the positional instability of an AP on system performance is then investigated. Vertical, horizontal, and inclined movements of the AP are examined and their effect on the number of users the system is able to accommodate is quantified. The altitude and displacement errors of the position of the AP have only a minor effect on capacity. For example, altitude errors of ±0.5 km, and displacement errors of ±0.3 km results in a reduction in the number of users of between 1 and 2%. The most sensitive parameter is the inclination, and an angular error of 5o causes the capacity to decrease by 38%. A system to control and compensate for the inclination error is proposed.</p
Testing of Level Shifters in Multiple Voltage Designs
No full textThe use of multiple voltages for different cores is becoming a widely accepted technique for efficient power management. Level shifters are used as interfaces between voltage domains. Through extensive transistor level simulations of resistive open, bridging and resistive short faults, we have classified the testing of level shifters into PASSIVE and ACTIVE modes. We examine if high test coverage can be achieved in the PASSIVE mode. We consider resistive opens and shorts and show that, for testing purposes, consideration of purely digital fault effects is sufficient. Thus conventional digital DfT can be employed to test level shifters. In all cases, we conclude that using sets of single supply voltages for testing is sufficient
HSPICE implementation of a numerically efficient model of CNT transistor
No full textThis paper presents the algorithms of an implementation of a numerically efficient carbon nanotube transistor (CNT) model in HSPICE. The model is derived from cubic spline non-linear approximation of the non-equilibrium mobile charge density. The spline algorithm exploits a rapid and accurate solution of the numerical relationship between the charge density and the self-consistent voltage, which results in the acceleration of deriving the current through the channel without losing much accuracy. The output I-V characteristics of the proposed model have been compared with those of a recent HSPICE implementation of the Stanford CNT model and published experimental I-V curves. The results show superior accuracy of the proposed model while maintaining similar CPU time performance. Two versions of the HSPICE macromodel implementation have been developed and validated, one to reflect ballistic transport only and another with non-ballistic effects. To further validate the model a complementary logic inverter has also been implemented using the proposed technique and simulated in HSPICE
