A Survey on PiCode: Picture-Embedding 2D Barcode

In this Review paper discusses about the last few years, conventional Two-Dimensional (2D) barcodes and some existing beautified QR codes. Quick Response (QR) code is widely used in many applications such as marketing, for industrial applications, retail applications, health care applications, manufacturing, and product tracking etc.This paper explains the basic concept of QR images, i.e. a recently proposed beautified QR code. We focus on revising preprocessing methods by proposing block division and source & channel coding methods. In the traditional decoding procedure decoding steps consist of image binarization, corner detection, perspective transformation and error correction. So the existing barcodes have some limitations, so the new picture-embedding 2D barcode system: Picode proposed. PiCode technology improves the aesthetic value of the picture embedded barcode. To preserve both the perceptual quality of the embedded image and the decoding robustness of the encoded message PiCode is designed with careful considerations. Advantage of using PiCode in advertisement business to link customers in a more interactive, interesting, and unique way. So the PiCode enable pictures/logo to be integrated with a 2D barcode to achieve enhanced visual appearance and high decoding reliability

Development of Plastic Injection Mold using Simulation Technique Analysis Result

Abstract: This paper deals with the development of Plastic Injection Mold using Simulation Technique results. In analytical solution Simulation and analysis is carried out with the help of mold flow software. In this work we use Autodesk mold flow software. From the simulation and analysis, the software for flow simulation provides sufficient information regarding filling time, injection pressure, defects like air traps, weld lines, sink mark, warpage etc. With these results, users can avoid the defect of the plastic in actual injection. The analysis will help the to design a mold with minimum modifications and which will also reduce the time and cost. The design will be validated by producing the component with the help of the designed mold

Microwave-Assisted Synthesis of Titania Nanocubes, Nanospheres and Nanorods for Photocatalytic Dye Degradation

TiO2nanostructures with fascinating morphologies like cubes, spheres, and rods were synthesized by a simple microwave irradiation technique. Tuning of different morphologies was achieved by changing the pH and the nature of the medium or the precipitating agent. As-synthesized titania nanostructures were characterized by X-ray diffraction (XRD), UV–visible spectroscopy, infrared spectroscopy (IR), BET surface area, photoluminescence (PL), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and atomic force microscopy (AFM) techniques. Photocatalytic dye degradation studies were conducted using methylene blue under ultraviolet light irradiation. Dye degradation ability for nanocubes was found to be superior to the spheres and the rods and can be attributed to the observed high surface area of nanocubes. As-synthesized titania nanostructures have shown higher photocatalytic activity than the commercial photocatalyst Degussa P25 TiO2

Purified cellulose, soybean hulls and citrus pulp as a source of fiber for weaned piglets

Dietary fiber is an important component, which has a direct effect on intake, digestion, and absorption of nutrients; and also alters intestinal microbiota and morphology according to solubility. One digestibility trial and one performance experiment were performed to evaluate the effects of sources of fiber in diets for 21 day weaned piglets. The experimental diets used in both trials consisted of a control diet and diets with purified cellulose, soybean hulls or citrus pulp as a main source of dietary fiber. To evaluate the digestibility of nutrients (Assay 1), the total feces and urine collection method was used. The fiber sources did not affect nutrient digestibility, except for soluble fiber, which increased with the inclusion of citrus (Citrus sinensisL.) pulp. To evaluate performance, morphophysiology and microbiology of the digestive tract of weaned piglets, a total of 32 castrated male piglets was used. Slaughter of animals was implemented at 35 and 50 days of age. The use of soybean (Glycine max L.) hulls and citrus pulp in diets increased the number of goblet cells and the density of villi in the jejunum. The viscosities of stomach and cecum contents increased due to the addition of citrus pulp. Soybean hulls and the citrus pulp included in diets reduced the occurrence of E. coli in the small intestines of piglets slaughtered at 35 days of age. Among the fiber sources, purified cellulose in piglet diets promotes better performance of animals, due to the modulation of the small intestine microbiota, with lower E. coli occurrence resulting in higher villus density

Towards a holding environment -building shared understanding and commitment in projects

Abstract Purpose: The early stages of projects are often characterised by ambiguity arising from differences in stakeholder views regarding project rationale and objectives. This paper presents a viewpoint on how to build a shared understanding of project goals and thus reach a shared commitment to achieving them. One of the ways to achieve shared understanding is through open dialogue, free from political and other constraints. We call an environment that fosters such dialogue a holding environment. Our main aim is to illustrate, via a case study: 1. How an alliance-based approach to projects can foster a holding environment. Design/methodology/approach: Following a discussion of theoretical background and literature review, an alliancing case study is used to illustrate the development of a holding environment and demonstrate the utility of IBIS in the creation of such an environment. Findings: It is seen that an alliance-based approach to projects can provide the foundation for a holding environment. IBIS is seen to facilitate the building of shared understanding by making arguments explicit and capturing decision rationale. Practical Implications: The paper outlines a practical framework for improving the quality of dialogue and achieving stakeholder commitment on projects. Originality / Value: Achieving shared understanding and commitment to action is difficult, particularly in the early stages of projects. The paper outlines the conditions and techniques needed to facilitate this via a non-trivial case-study

Modification by habitat in the Portuguese Oyster Ostrea (Gryphcea) angulata

While working on the beds in the River Blackwater, Essex, a collection of Portuguese oysters, which had been dredged along with native oysters (O.edulis) from the river and creeks, was seen at a glance to show a distinct average difference in shape from the usual type of Portuguese oyster. The ordinary Portuguese oyster as seen exposed for sale is usually im-ported when quite small, or occasionally well-grown, and relaid on English beds at or above low-water mark to grow and fatten. Orton∗ has shown by definite experiments on the same beds that the Portuguese oyster spawns and spats in English waters in favourable (hot) weather. There can be no doubt, therefore, that the Portuguese oysters dredged had grown in situ from larvae which had developed in the waters of the river and creeks. In Portugal and France the Portuguese oyster is stated to occur at and just below low water springs (see Bashford Dean, Bull. U.S.F.C. XI, 1891 (1893), p. 368), and is apparently hand collected at the present day for export purposes. A difference in shape in native oysters is very common, but Bell and others have so far found it a very difficult matter to correlate any particular shape with a particular environment. Indeed, Bell stated, in a letter, that each locality seems to have its own type of shell-growth in the native oyster. Such a difference as that noted above in the Portuguese oyster was therefore deemed worthy of some attempt at expression

Performance Analysis of Lte Network Using Runtime Pre-coding Algorithm

LTE (Long Term Evolution) meets the requirement of high data rates, improved end user performance, better spectrum utilization, no interference and many more. All this is possible because of its features, one of which is multipoint transmission with single user as well as multi user. But whenever user receives signal from number of transmitting a points, it becomes difficult to calculate the precoders and corresponding filters. The paper describes one of such scenario where user receives signal from multiple eNodeBs. We have implemented a runtime algorithm to estimate the pre-coders and its corresponding filters for system level simulation of LTE network using Matlab
