Almost 90% of all the data in the world has been generated over the last few years. In this vast ocean of data, how does one find relevant information? How do readers verify the credibility of information? In the realm of real estate, how do house hunters trust house listings? GoLocal is a real estate website that resolves some of these questions. I intend to develop GoLocal – an innovative real estate website to provide services not provided by any other existing websites, such as StreetEasy, Zillow, Trulia etc. GoLocal is primarily for international students looking for accommodations in a foreign place. It will offer hot deals, a personal assistant that will help them in finding a place and other discounts and privileges for students. The website will provide listings based on the user's requirements. The unique feature of GoLocal is that listings are 100 percent verified and authentic. It will also offer other features like ...

There are so many algorithms which are available for face recognition .There are two approaches by which the face can be recognize i.e. face Geometry based and face appearance based. The appearance based technique is also sub divided into two technique i.e. local feature and global feature based. The technique of local feature based are Discrete Cosine Transform (DCT).In this paper we study the two global features (holistic) appearance based algorithm i.e. Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) in which every face image is converted into 1D, we are using 1D for all the calculation and then compare these two algorithm with the help of FAR (False Acceptance Rate),FRR (False Rejection Rate),Time, Memory and checks which algorithm gives the

This paper proposes the method to make traffic signals intelligent with the dynamic signal values on the basis of different parameters. This method shall drastically reduce time, fuel and also suggest alternate routes that are congestion free. There are different adaptive strategies for traffic control but with their limitations of particular region and junctions, it is required to make it more precise for a specific network of junctions. For creating the real traffic scenario, consider that all vehicles are equipped with the Bluetooth devices. Our proposed algorithm shows the dynamic traffic control and traffic profiling for the given time.

Although, there are many alternatives available to the farmers but none of these is significantly adopted by them. Happy Seeder Technology (HST) was introduced to tackle the problem of paddy straw burning. The study was conducted to find the rate and extent of adoption of HST among the farmers by characterizing the extension efforts. One hundred and eighty HST adopter farmers were selected from the five agro-climatic zones Punjab. Average area under HST was about 58 per cent of the total operational land holdings of respective farmers. From awareness to adoption average forty months were taken by the farmers to complete the five stages of adoption process. Attributes of the technology viz. relative advantages, trialability, observability and compatibility had positive effect on the rate of adoption. Extension activities, easy availability of HST and large operational land holding had a positive effect on...

However, different types of biomasses have different mechanical properties to be pelletized, which entails a limitation in available raw materials for pellet producers. Within this study eleven different pure substances from biomasses were separately mixed with European beech and Scots pine, to identify its impact on the densification process. Beech and pine pellets were used as control materials against their corresponding pellets mixed with substances representing: cellulose, hemicelluloses, other polysaccharides, lignin, protein, and extractives. The mechanical properties were investigated as well as FT-IR and SEM analyses on the pellets. The results showed that the addition of the substances xylan and galactan created the hardest pellets for both pine and beech and that adding extractives to wood affects pine more than beech in relation to hardness. The FT-IR data could no...

The effects of cardioplegia on renal function have not been well defined. We compared the effects of St. Thomas No. 2 cardioplegia solution modified with lidocaine or procaine and found no statistically significant difference in between the two groups. We carried out further multivariate testing adjusting for diabetes and found no statistically significant changes in renal function between the two groups.

It is due to the deposition of homogentisic acid (HGA) commonly found in alkaptonuria. Ochronosis in the aortic valve is a rare occurrence and there is limited data available on the most appropriate choice of valve prosthesis in these patients. This case involves a 72-year-old male with symptomatic aortic stenosis and on echocardiogram a severe calcific trileaflet aortic stenosis with normal ejection fraction. Intraoperative aortic cannulation was routine and uncomplicated, and bluish-black discolouration of aortic valve was noted. Thorough decalcification was undertaken and a bioprosthetic valve was chosen in accordance with patient's age and preference. There were no complications post-operatively and the patient reported being well. Ochronosis affecting the aortic valve is a rare condition and there is limited data on the recurrence rate as well as the natural history of the disease. This case reports aims to provide data to facilitate further research to better understand the natural history of aortic valve ochronosis and rates of recurrence following bioprosthetic aortic valve replacement (AVR).

With the advent of cloud computing, many ecosystem and business paradigms are encountering potential changes and may be able to eliminate their IT infrastructure maintenance processes. Real-time performance and high availability requirements have induced telecom networks to adopt the new concepts of the cloud model: software-defined networking (SDN) and network function virtualization (NFV). NFV introduces and deploys new network functions in an open and standardized IT environment, while SDN aims to transform the way networks function. SDN and NFV are complementary technologies; they do not depend on each other. However, both concepts can be merged and have the potential to mitigate the challenges of legacy networks. In this paper, our aim is to describe the benefits of using SDN in a multitude of environments such as in data centers, data center networks, and Network as Service offerings. We also present the various challenges facing SDN, from scalability to reliability and security concerns, and discuss existing solutions to these challenges.

The positive yield with brush before biopsy was 87.5%, with suction cytology 90%, with brush after biopsy 100% and with endoscopic biopsy 90%. Difference in the yield of brush after biopsy compared to other modalities was statistically insignificant (P > 0.05). However, the quantitative yield of the material was significantly high (P < 0.05) in the brush after biopsy compared to brush before biopsy. Of these three cytological modalities brush after biopsy appears to be the cytological technique of choice to be used as an adjunct to endoscopic biopsy.

Right axillary artery cannulation can add up to one hour to the procedure and risk damages to brachial plexus and hyperperfusion syndrome to right arm. We reviewed our recent experience of antegrade unilateral cerebral perfusion through the brachiocephalic artery with moderate hypothermic circulatory arrest using the retrograde cardioplegic cannula. Method: Between January 2005 and August 2008, 19 patients underwent aortic surgery with unilateral antegrade selective cerebral perfusion through the brachiocephalic artery and moderate hypothermic circulatory arrest. Patients' mean age at the operation was 60.6 ± 11.6 (32-82) year-old. Ascending aorta or hemiarch replacement was performed in 7 patients, aortic root replacement plus ascending aorta or hemiarch replacement in 11 patients and total arch replacement in 1 patient. Surgery for acute aortic dissection was 5 patients. All operations were approached through a median sternotomy. Cardiopulmonary bypass was started with the femoral artery or the ascending aorta or the distal arch and right atrial cannulation. The heart was vented through the right superior pulmonary vein. While the patient was cooled to 22-28 • C, proximal anastomosis was performed. Then the patient was arrested. The brachiochephalic artery was cannulated using a balloon tipped 15Fr catheter used for retrograde cardioplegia. The right carotid artery and the left subclavian artery were not clamped. Antegrade unilateral cerebral perfusion was established at the rate of 700 ml/min of cooled blood using a single roller pump separate from systemic circulation. The pressure of the catheter tip was monitored, which was controlled between 50 and 70 mmHg. Before completing anastomosis, perfusion cannula was removed. The whole patient was perfused through side arm of the graft. When patient was fully rewarmed, cardiopulmonary bypass was withdrawn. Results: There were no operative deaths and no permanent neurological deficits. Three patients had a temporary neurological problem such as confusion or delilium. Mean cardiopulmonary bypass time was 120 ± 20.8 (81-154) min. Mean antegrade cerebral perfusion time was 21.6 ± 8.0 (12-48) min. Mean cardiac arrest time was 68.3 ± 17.1 (40-95) min. Eight out of 20 patients had circulatory arrest at 28 • C and their mean circulatory arrest time was 22.8 ± 4.7 (16-32) min. Discussion: Mortality and neurological results of aortic surgery using unilateral antegrade cerebral perfusion with moderate hypothermic circulatory arrest was satisfactory.

A 69-year-old woman presented in pulmonary oedema. She was found to have a large left atrial myxoma prolapsing into the left ventricle in diastole causing severe functional mitral stenosis. At operation, the myxoma was completely excised from its attachment to the atrial septum. The mitral valve looked anatomically normal but the mitral annulus was dilated. The intraoperative Trans Oesophageal Echocardiogram (TOE) on weaning from cardiopulmonary bypass confirmed a dilated mitral annulus with moderate mitral regurgitation (MR). We elected not to place an annuloplasty ring in anticipation of improvement with postoperative remodelling. However, mitral regurgitation worsened after discharge becoming moderately severe and remains so after 1 year follow-up despite optimal medical treatment. This case suggests that annular dilatation can result from mechanical dilatation by a large left atrial myxoma. Intraoperative mitral valve annuloplasty should be considered in the presence of moderate MR as postoperative remodelling does not occur.
