AES-CBC Software Execution Optimization

With the proliferation of high-speed wireless networking, the necessity for efficient, robust and secure encryption modes is ever increasing. But, cryptography is primarily a computationally intensive process. This paper investigates the performance and efficiency of IEEE 802.11i approved Advanced Encryption Standard (AES)-Rijndael ciphering/deciphering software in Cipher Block Chaining (CBC) mode. Simulations are used to analyse the speed, resource consumption and robustness of AES-CBC to investigate its viability for image encryption usage on common low power devices. The detailed results presented in this paper provide a basis for performance estimation of AES cryptosystems implemented on wireless devices. The use of optimized AES-CBC software implementation gives a superior encryption speed performance by 12 - 30%, but at the cost of twice more memory for code size.Comment: 8 pages, IEEE 200

Seeds for Change: Examining the Association between Race, Food Security, and Urban Agriculture

Access to healthy, nutritious food is one of the most basic human needs. Unfortunately, a large portion of the global population, including that of the United States, has limited access to such food, hence putting families in a state of food insecurity. Food insecurity occurs when households are unable to (or struggle to) provide adequate food to all household members due to lack of funds or food resources. This phenomenon is considered to be a major concern in many urban settings such as Detroit, as it is a characteristic of societal distress. Interestingly, research has shown that while food insecurity is widespread, it has greater prevalence amongst minority groups who report higher rates of food insecurity when compared to their white suburban counterparts (“Food security in the United States”, 2011).This leads one to ask, what is the connection between food security and race? Analyzing this issue reveals a structural conflict within society which works to the advantage of some racial groups at the expense of others. While urban minorities experience food insecurity, a shift towards urban agriculture is underway that aims to ameliorate structural inequality in the food system. This study investigates the links between race and food security as well as the urban agricultural movement as a response to an inadequate food system, especially that which exists in Detroit

Home Away From Home

Home away from home is an e-commerce application for short stays of homes or apartments. It allows property owners to advertise and lease them for a short period of time. It has three different account types: one for e-commerce admin, second for owner who wants to lease his/her property and third for someone who wants to rent a property. The functionalities of this application include uploading photos, setting preferences, auditing, property listings, bookings, payment processing, post-rental ratings, surveys and web mapping. The renter can search for properties based on ratings and reviews, property owner can manage property reservation, e-commerce admin specifies authority and restrictions on the users. The main goal of this application is to make the job easy allowing everyone to perform quick transactions like for the Owner to manage the property details, Customer to quickly get good deals followed by easy checkout and Administrator to manage properties and financial details. Many such functionalities have been embedded to explore, book and travel benefitting the user

Online Art Gallery

Online art gallery is an e-commerce application which connects artists with their customers, this website will help the artists to showcase their art in this website by helping them to sell it to prospective customers also it will help the customers to discover and search the art which they like and they will have an option to buy the art if they want.

Morphometric studies on the embryonic gall bladder and cystic duct of Gaddi Sheep in different prenatal age groups

The objective in the present study was to reconnoiter the morphological structure and biometrical parameters of embryonic gallbladder and cystic duct during the fetal life of Gaddi sheep. A Total number of 40 Gaddi sheep foetii samples were collected irrespective of sex and without any external anomaly or pathology. The age estimation of each foetus was done and accordingly the foetii were grouped as; group-I (1-60days), group-II (61-90days) groupIII (91-120days) and group-IV (121 –full term). The gall bladder from each foetii were excised hygienically. Gall bladder appeared at Crown Rump Length CRL 6.0 cm (46 days of gestationl age) and was slate blue colour in fresh state and settled into the visceral surface of right lobe of liver. It had single opening which continued as cystic duct. The maximum length and width of gall bladder (1.85 cm and 0.75 cm respectively) and cystic duct (1.68 cm and 0.18 cm respectively) increased with the advancement of gestational age
