One of the assumptions for an economic order quantity model is that all items received in an order are of perfect quality is not always fulfilled. Some of the items are of defective quality in the lot received. Another assumption is that as soon as items are received, payments are made. In today’s competitive the supplier allows certain fixed period known as permissible delay for payment to the retailer for settling the amount of items received. Keeping this reality, a deterministic inventory model with imperfect quality is developed when deterioration rate is different during a cycle. Here it is assumed that demand is a function of time and price. Numerical example is taken to support the model. Sensitivity analysis is also carried out for parameters.

Cotemporary development has transformed the city structure and urban fabric. Several studies in public health domain contemplate premeditated active transport as one of the major decisive factor in enhancing urban dwellers’ quality of life. Active transport and human powered transportation includes walking, cycling and variants such as cycle rickshaws, skateboards, push scooters, hand carts, etc. These modes provide both transportation and recreation and are especially important for short trips that form the largest share of trips in urban areas. Since the built environment is the setting in which the use of active transport manifests, if a sufficient condition is not provided, it may deprive the individuals of any opportunity for the activity to occur at all. This is why it is important to study the built environment as a factor of walkability and develop knowledge about creating urban environments that are conducive for active transport. This paper discusses active transport factors at various levels. Further, the paper dwells on investigating the attributes of built environment at the street and building level.

In this study, we examine the combined effects of thermal radiation, chemical reaction on MHD hydromagnetic boundary layer flow over a vertical cone filled with nanofluid saturated porous medium under variable properties. The governing flow, heat and mass transfer equations are transformed into ordinary differential equations using similarity variables and are solved numerically by a Galerkin Finite element method. Numerical results are obtained for dimensionless velocity, temperature, nanoparticle volume fraction, as well as the skin friction, local Nusselt and Sherwood number for the different values of the pertinent parameters entered into the problem. The effects of various controlling parameters on these quantities are investigated. Pertinent results are presented graphically and discussed quantitatively. The present results are compared with existing results and found to be good agreement. It is found that the temperature of the fluid remarkably enhances with the rising values of Brownian motion parameter (*Nb*).

The idea of designing a micro level artificial gecko adhesive structure is inspired from ability of geckos to climb any surface. Gecko can climb any rough or smooth surface because of its hierarchical structure present on feet which functions as a smart adhesive [1]. The key parameter that affects gecko adhesion are pattern periodicity of a synthetic setae, hierarchical structure, length, diameter, angle, size, stiffness of end tips and flexibility of a base [2]. The design and fabrication of number of single and multi-level hierarchical pattern were performed. CO2 LASER cutting machine having power of 60 W is used to manufacture moulds. The mould is fabricated from methyl methacrylate sheets of different thickness 3 mm to 10 mm. Liquid silicone polymer PDMS is used as a cast material. Various patterns having dimensionsupto200 micrometer with different tip shapes and geometries were fabricated. For single level patterns like dense pattern, mushroom shape pattern and wedge pattern (lamellar structure) were fabricated. Attempts were made to design and fabricate Multi-level hierarchical structure patterns that mimics gecko like foot structure. These micro level artificial gecko structure have large scope of applications such as climbing robots, non-sticky adhesion tapes, military surveillance and even medical applications.

This paper presents a new approach called Seam Carving for multirate signal processing of digital images. Increasing and decreasing the sizes of digital images are common place in day-to-day image processing. These methods involve long procedures and sometimes consume more time for getting implemented. Whereas, using the Seam Carving method eradicates the excess time involved in upsampling and downsampling a digital image considerably as this method is straightforward and simple to implement. This method comes in handy when we are dealing with large medical images and remotely sensed images. This technique is applied on standard images and its performance is analyzed. The entire work was implemented using Matlab R2017a software package.

Effect of blast loads from explosion can be mitigated by using thick armor systems that are often heavy and significantly increase the self-weight of the structure. In the design of structure for blast protection, sacrificial claddings which consist of high energy absorbing elements are used. A sandwich type protective structure consists of light weight core which is often used for blast mitigation. The choice of core type has an influence on the performance of sandwich panel. The cores can be of wood, foam material and tubular elements. In this study, behavior of sandwich panel with square tubular core is investigated through numerical studies. Panel is made of mild steel having top plate dimension of 150 mm x 150 mm x 2.5 mm; bottom plate of 150 mm x 150 mm x 5 mm and square tube core of 12.5 mm x 12.5 mm with 0.6 mm thickness. A finite element model is developed and validated using experimental results in literature. Parametric studies are carried out using the validated finite element model. By varying the tube length of the core, the responses of the panels in terms of energy absorption and reaction forces are compared.

Energy demand always lags energy supply in developing countries, which results in energy crisis. The conventional energy sources are finite and exhaustible. The solution to problem of energy crisis is utilization of renewable energy. Renewable energy sources are usually found in small scale, decentralized with regard to different geographical distribution, transition to renewable energy sources is viable option as the price of oil and gas continues to fluctuate. As an alternative to custom, onsite construction of centralized power plants, renewable systems based on PV arrays, windmills, Biofuel energy based systems or small hydropower, can be mass-produced “energy appliances” capable of being manufactured at low cost and tailored to meet specific energy loads and service conditions. , to make optimum utilization of renewable energy there exists a need to integrate the different renewable energy systems. The present work involves development of Renewable Energy based hybrid system for electricity generation that can supply desired power continuously throughout the year irrespective of fluctuation of energy available from standalone systems. The energy assessment has been done using Homer simulation tool for developing small solar-wind hybrid system, performance evaluation has been done.

I. INTRODUCTION Roads are constituted as the most significant component of India’s Logistics Industry, accounting for 60 percent of the total freight movement in the country. A majority of players in this industry are small entrepreneurs running their family businesses. As a result, Man Power Development Investments that pay off in the longer term, have been minimised respectively. Moreover, these businesses are typically controlled severely by the proprietor and his / her family and consequently, making it unattractive for the professionals. Poor working conditions, Low pay scales relative to alternate careers, poor or non-existent Manpower Policies and prevalence of unscrupulous practices have added to the segment's woes for seeking employment. Thus, it could be rightly stated that the Transportation, Logistics, Warehousing and Packaging Sector is considered an unattractive career option and fails to attract and retain skilled manpower. Many Organizations have failed to recognize that Human Resources play an important role in gaining an immense advantage in today’s highly competitive Global Business Environment. While all aspects of managing Human Resources is important, Employee Retention continues to be an essential part of Human Resource Management activity that help the Organizations to achieve their goals and objectives.

I. INTRODUCTION International Marketing is an important perception for various economies and countries of the World. The 90’s decade saw a significant change in the structure of International Marketing. Technology has changed with many new advancements and innovations. This has resulted in having better transport system, good communication methods which in turn has brought the whole world together and made it so small. Liberalization, privatization and globalization have made the term Global Market very significant in nature. This meant company could produce larger quantity of goods at cheaper rates just because of technical and technological changes. That’s why many companies are now forced to look beyond their domestic boundaries to get entry in global markets. Newer market meant bigger challenge to conquer them. This has made international marketing indispensable.

To use waste materials as alternatives in construction industry is an innovative thought. Now a day’s many wastes are used in construction industry like in cement production, for manufacturing of concrete and also for manufacturing of bricks. In all types of thermal power plants large amount of fly ash is librated. Which causes air pollution. So to minimize the quantity of generated waste material we are using it in construction. In this paper fly ash from different sources are taken to prepare the concrete. And in this cement is 100% replaced and for creating the bond in it NaOH and Na2SiO3 solution is used. Which form geopolymerisation process and acts as a replacement of cement in the mix. In the present work, OPC is totally replaced, But cement is working as a binder in the concrete mix. The main task is now to form another binder in the mix, as there is 0% cement. Hence, NaOH (Sodium hydroxide), Na2SiO3 (Sodium silicate in the form of flakes), super plasticizer (Sulphonated naphthalene polymer based super plasticizer) is used in the distilled water. By using NaOH & Na2SiO3 in distilled mix in the concrete, polymerization process takes place which form gel in the mix and which works as a binder in it, after making concrete specimens of 8M (Molarity) & 12M (Molarity) with the different fly ashes, specimens are treated with ambient (temperature) curing at 7 days and 28 days. And at the age of 7 and 28 days strength is tested (Compressive and Flexural strength) After the (specimens) test results, it is concluded that NTPC Sipat fly ash based specimen gives more satisfactory results of compressive and flexural strength as compared to GMR Tilda fly ash based specimen. And also at 12 Molarity concentration of NaOH solution compressive and flexural strength increases as compared to 8 Molarity. Hence it is said that while increasing the concentration of NaOH solution in terms of Molarities (8M to 12M), strength of the specimens increases.

An online oil spill advisory(OOSA) system was developed for the first time in India, at Indian National Centre for Ocean Information Services (INCOIS) to serve the coastal community, regulatory authority and oil spill responders. It is achieved by triggering the oil spill trajectory model through web-interface. OOSA receives the inputs from the users in html feeds. Once after the submission of inputs, it automatically triggers the oil spill trajectory model and delivers the drift pattern of the pollutant at regular intervals, without the support from modeling community or officials of INCOIS. It is completely an automated set up. The system comprised the diagnostic mode of General National Oceanic and Atmospheric Administration (NOAA) Operational Modeling Environment(GNOME) in batch, which is triggered through web interface with the details such as, location, date & time of the spill, quantity, type of the oil spilled. The forecasted wind forcing and the current forcing obtained from our ocean state forecast(OSF)laboratory, were tuned and set in the prescribed format on daily operational basis. The generated trajectory is layered automatically on a webmap, so that the zones that are likely to get affected are known. Trajectory predictions were made online for the oil spill occured at Sundarbans delta during 09.12.2014 to 15.12.2014. The oil slicks were noticed within 1.3 km from the predicted locations. This paper explains the simulation of an oil spill trajectory model for getting the drift pattern of the pollutant at sundarbans delta, through web interface. The method of interpreting the results are also explained. This OOSA system is made available online, so that the users can utilize this during oil spills, mock drills and for preparing the local contingency plans. This system will also guide the oil spill responders, to manage and plan the response activities during the event of an actual or a hypothetical oil spill.
