The operation of transportation determines the efficiency of moving goods or products. Many firms spent more amounts for the transportation in their total cost of the supply chain. The fuel charges play an important role in thesuccess of transportation for transporting the goods from the origin to destinations. So in this paper we present a three echelon inventory model with Variable Transportation and Variable Carbon emissions along with the fuel charges. Mathematical model and the numerical examples also were presented for the proposedmodel.

In this paper, for the products with variable production cost and selling price and different distribution of customer demand, an optimization model is established. Producing the similar type of products at the uniform cost may not attract the customer demand always. Instead of stabilizing the distribution of products according to the customer demand, it is an important one to design the model for enabling the products to produce at the variable cost of production, at the multiple price of sales and also at the altered distribution towards the demand for the main objective of optimizing the level of profit. On the other hand, the model is proposed with the assumption that the customer demand is not identical with the production costs ,selling price and the supply of the items . In this study, limited production quantity and uniqueness of the products are considered. An optimization is achieved in producing, selling and distribution of costs, price and goods respectively. An illustration is presented for practicing in application on this model and graphical explanation is also provided to describe this model.
Keywords: Multiple production quantity- Variable cost of production , selling price and Distribution – Customer Demand – Optimization.

In inventory every production batch contains a fraction of defective items. This paper discusses the economic production quantity inventory model with rework process at a single stage production system with planned backorders. The imperfect quality items are detected from the inspection process, so we added the inspection cost in the total system cost along with we developed the inventory model with three different density functions such as uniform, triangular and beta. The numerical examples are given to illustrate the proposed inventory models.
Keywords: EPQ, imperfect production system, rework, inspection cost, planned backorders.

Flow forming is an advanced chip less incremental metal forming process, which employs point deformation technique used to produce dimensionally precise long tubes. In this study, a fully annealed Aluminum Alloy 6061tubular preform was cold flow-formed by using three rollers with a single pass forming. In this study, effect of flow forming process parameters viz; feedspeed ratio, percentage of reduction and roller axial stagger on thickness variation have been analyzed. It is found that with increased feed rate, percentage of reduction and axial stagger the thickness is varying along length and also circumference of formed tube. The flow formed component has been analyzed using Design of Experiments technique (ANOVA) to find most influence factors; axial stagger and percentage of reduction on thickness variation and MINITAB software is used for multiple regression equation is formulated for estimating predicted values of thickness variation analysis.

This paper presents the implementationof aPolyaniline (PANI) based pellet monopole antenna for broadband applications. Polyaniline is synthesised by oxidative polymerisation and the conductivity is enhanced by secondary doping. The antenna is designed for an operating frequency of 6.8GHz. and it has a bandwidth of 1.42GHz .The dielectric substrate used is FR4 which has a dielectric constant of 4.4 and a loss tangent of 0.001.The conducting polymer used has a conductivity of 2000 S/m.The proposed antenna shows a gain of -2 dBi for a PANI thickness of 1.2mm.

Malicious software, referred to as malware, is one of the major threats on the Internet today. Due to vast use of Internet it found that many system are infected from malware which in form of computer virus, Trojan Horse, Worms, Rootkit, backdoor, evasion etc. In this paper we reviewed different approaches for malware analysis. Malware Analysis and classification with machine learning techniques is also discussed. This paper aimed to provide introduction about malware and its related issues.

This study assessed the impact of firing temperature on compressive strength of lateritic bricks. Twenty lateritic bricks samples of size 290mm x 140mm x 100mm were produced from the lateritic soil sample collected from a borrow pit along Ibadan-Lagos expressway, Southwestern, Nigeria. The geotechnical characteristics and classification of the lateritic soil sample were established. The bricks produced were fired at temperature 0oC to 950oC at 150oC interval after 28days of curing. The compressive strength of the fired bricks was determined. The result of geotechnical test carried out on the soil sample showed that the soil is laterite having a clay content <30%, extremely low gravel <10% and sand content of 83.33%. The Atterberg's limit test gave the liquid limit as 48%and plastic index 18.78%. The soil has natural moisture content and specific gravity of 34.92% and 2.64 respectively. The result further indicated that weight of the brick before and after firing is insignificant and the relationship between the weight and the firing temperature is inversely proportional. The result also revealed that the compressive strength of the fired brick is directly proportional to the firing temperature. Compressive strength of the bricks after firing ranges from 0.92N/mm2 to 2.24N/mm2 for various temperatures ranging between 350oC to 950oC. The result obtained from the tests was compared with the specifications of Nigerian Building and Road Research Institute (2006), Nigerian Building Code (2006), and Nigerian Industrial Standards (2000). The results indicated that the compressive strength of the fired brick at 950oC fall within the range of 225mm and 150mm sandcrete hollow blocks recommended compressive strength for building construction. The value varies from 1.59 N/mm2 to 4.25N/mm2 and 1.48N/mm2 to 3.35N/mm2 respectively, as the curing age increases from 7 to 28 days. Therefore a fired brick at 950oC is recommended for building construction especially as wall partition element. This will help both urban and rural dwellers that cannot afford to build a house with cement block. It will most especially benefit farmers toward building their storage room which could encourage increase in production of crops. This will invariably be helpful at this time of economic recession.
