This article Based on case study in Sanaye Felezi Iran Co. in this research, introduce a model in order to the production balance with the aim of improving for total expected cost. In the first step of research, introduce a linear programming model to determination the number of production in any production department. In the second step, by using the Hungarian allocation technique, the operator was allocated to any work stations. In the third step, introduce a Transportation programming model with the aim of improving for raw materials cost to any production departments. In the fourth step, with the use of ‘technique for order preference by similarity to ideal solution’ (TOPSIS), to determination the best transportation route, classifying material transportation routes from warehouses to assembly shop.

In this article based on case study in shelter assembly shop in Sanaye Felezi Iran Co, with the use of "Stop -Watch" method, the cycle time of every conveyance operation to each workstation of the assembly lines is measured then the standard time of every conveyance cycle, the ideal rate of conveyance, the velocity of conveyance in each minute, are calculated. Then, with the use of linear programming technique, decrease the total expected cost of conveyance. In the next stage, by using the Hungarian allocation technique, for each line of assembly shop, lifter and the operator was allocated and in the next stage classifying the raw materials transportation paths from warehouses to assembly shop to determination the best transportation path by use of ‘technique for order preference by similarity to ideal solution’ (TOPSIS). Finally, usage of production distribution model to optimum distribution of productions in Sanaye Felezi Iran Co.

This research about the use of integration and minimization of supply chain and logistic total expected cost model in Sanaye Feleziye Iran Co. In previous research that be done in this company, focus only on supply, production and distribution models or the combination of two models from these models, but there is no review the relationship between these three models. This issue is very importance because integration of total expected costs in terms of supply, production and distribution is the main reason for reduce of total expected costs. This research includes of the use of supply, production and distribution models and an integration model that is integrated supply, production and distribution systems.

The actual move bottom associated with rotor techniques, corresponding because helicopters, wind generators as well as propellers, includes a vortex multiply which is created by the pickup disbursement down the blades. Due to the co-action involving the vortex variables a new roll-up system adapts throughout instantly following vortex multiply is actually created, which often builds up corporation tip in addition to main vortices within the adjoining near-wake bottom your rotor. The actual roll-up system is actually centrally manipulated by the co-action legislations associated with Biot Savrt. In exceptional situations, your tip/root vortex system is actually alterable, in addition to oncoming in order to different lack of stability approaches the item by the way crumbles decrease in addition to commences small-scale disturbance in addition to downstream. The actual wake up can certainly normally possibly be alienated directly into 2 asymmetric areas, close to wake up in addition to a lot wake up. Near-wake variables tend to be accompanied on the starting up on the vortex system the spot that the living on the rotor is actually detected expressively throughout the putting your unit together on the vortex system. The actual a lot wake up is often your downstream route the spot that the wake up design no longer depends on distinct rotor capabilities as well as the spot that the move offers discontinued decrease and is particularly manipulated through small-scale disturbance. The actual start skepticism, while, are actually the best way to examine your relationship concerning near-wake design in addition to far-wake conduct. The actual design on the wake up offers used approaches with the aerodynamic conduct associated with helicopters (Bolnot 2010) in addition to wind generators (Vermeer, Sorensen & Crespo 2008) as well as pertaining to deliver propellers (Breslin & Andersen 1996).

In this paper folded printed dipole antenna with PBG operating for Ultra wide band applications ,The geometry of the antenna is very simple for fabrication and printed circuit board integration that is only 42*36 mm, the proposed antenna are simplified structure with 50 ? feed line .the PBG structure antenna working in the frequency at 3.2 GHz and 3.9GHz with the bandwidth 68% and 50 % respectively ,In this proposed antenna has maximum gain 4.664 dBi and 3.8 dBi at 3.2 GHz and 3.9 GHz respectively .The proposed radiation pattern is omnidirectional in the E-plane and H-plane due to the orthogonal configuration of the dipole strips. The folded printed dipole antenna with PBG structure antenna should be useful for the UWB applications, The radiation characteristics examined in further sections.

The National Radioactive Waste Management Centre was established in June 1995. The Centre is responsible for all national radioactive waste safety operations in Ghana at its centralized waste management facility. It also aims at promoting research and development activities in radioactive waste management in Ghana. Despite the myriad of challenges confronting the centre in executing these mandates it is however, making giant strides in the safe management of radioactive waste in Ghana.

The effect of fly ash additions on the mechanical properties of ceramic tile composition has been investigated. Fly ash addition in the range of 0-30wt% (Class-A) and 0-30wt% (Class-B) have been added into the tile body composition, wet milled, spray dried,shaped and fired at different temperatures (900, 1000,1050 and 1100 C). The MOR strength improved with increasing fly ash content and reached maximum when 30wt% (Class-A) and 20wt% (Class-B) fly ash used, and with greater additions it decreased. A linear correlation between strength development and Mullite formation was found. The tile with 30wt% fly ash (Class-A) and 20wt% (Class-B) have improved bending strength and have lowest porosities. The effects of fly ash incorporation on the mechanical properties of ceramic tiles and found that a small amount of fly ash addition improves the strength of the ceramic tiles.

Elderly become more vulnerable to malnutrition and ill health as they grow older. This study was done to assess the functional and nutritional status of institutionalized elderly. The study was conducted in 100 (65 females) elderly aged 78.6 ± 6.9 years. Males had higher height, weight, fluid intake and better functional status (p<0.05). Females had higher fasting blood sugar, HDL cholesterol and proteins (p<0.05). In Mini Nutritional assessment (MNA), females were found more malnourished (p<0.05). Institutionalized Males have better functional and nutritional status as compared to females.

Creativity plays an important role in learning and life for undergraduates who major in physics. There are many factors in physics help teachers to train students’ creativity. Teachers should have advanced education ideas about physics creativity education. There are several methods to foster students' creativity in physics instruction, such as strengthen the training of creative thinking, implement experiments and scientific practices, and grasp the principles of creativity.

Image compression has become a necessary step for making better use of available storage requirements and transmission bandwidth during the past decades. For image compression it is desirable that the selection of transform should reduce the size of resultant data set as compared to source data set. For continuous and discrete time cases, wavelet transforms and wavelet packet transform has emerged as popular techniques. This thesis paper aims to determine the best wavelet to compress the still image (fingerprint) at a particular decomposition level using wavelet transforms and wavelet packet transforms. Number of Zeros (NZ) and Retain Energy (RE) is determined for different wavelets at different threshold values ranging from 10 to 100 for decomposition level 3.
