High Betweenness Centrality

To reduce the likelihood that R&D projects fail, companies tend to perform collaborative R&D activities in networks. A fundamental characteristic of networks is stability. This paper introduces a novel approach that theoretically determines the stability of R&D networks and combines the analysis of network topology with a two-layer simulation model. Graph theory and measures from social network analysis are used to analyze the topology of collaborative R&D project networks. Our study enables us to identify the companies that play a key role in R&D networks. To ensure the right outcome of the collaborative R&D project, participants with a high betweenness centrality index should be monitored. These participants influence the stability of collaborative networks on a large scale. With these insights, an improved risk management approach can be set up.

Entering into the new field of business is not an easy go. One has to do market research, to identify the gap, to identify the product/service to be offered, and to target the right customer segment. After doing the required research, the next step is to make decisions on plant location, layout and then set up.  Assessment of funds required for capital as well as revenue expenditure, procurement of machinery and other materials also take substantial amount of efforts. Searching for vendors and finalizing the right one are few other issues. After having worked successfully for more than 30 years in Bali in the field of sesame seeds and oil business Harsh was standing on a crossroad in 2011. Rising prices of sesame oil resulted in shift in customers’ taste and preferences towards refined oil. Moreover entry of big players at a large scale of operations and rise in price of raw material (sesame seeds) made survival tough. He had a number of options, one to continue with existing business at different scale of operations. Two, enter another business? Three, what business, Four, which place? The case talks about Harsh’s journey to new business, his choice and then the result.

The routing protocols in MANET are mainly classified into two type’s i.e. pro-active and reactive based protocol based on its problems in the network. One of the prime and foremost issues, which have gained a lot of scope, is its dynamic nature of the networks i.e. the stability of nodes is not guaranteed in the network. Hence, this leads to loss of data packets that needs for its retransmission. Many advancements and Novel protocols have been devised in recent years for efficiency and effectiveness in the ad hoc networks. However, hybrid routing proto-cols that inculcates the nature of reactive and proactive has gained a lot of importance. ZHLS is one of the Hybrid routing protocol, and is a two tier hierarchal routing that divides the area into zones in which mobile nodes move randomly. The process of promoting ZHLS protocol is purely based on homogeneous scenarios which mean the nodes in the network are statistically identical, but there is lack of studies for heterogeneous set-up where mobile nodes act in a different way in an identical network. In this paper, we try to propose a novel approach known as “Adaptive-ZHLS: AZHLS” that can be suitable for heterogeneous scenarios. Experimental set up and simulated results will show that AZHLS provides higher packet delivery fraction as compared with the traditional one.

Stability analysis and dynamic simulation are important for researchers to capture the performance and the properties of underling systems. S-systems have good potential for characterizing dynamic interactive behaviour of large scale metabolic and genetic systems. It is important to develop a platform to achieve timely dynamic behaviour of S-systems to various situations. In this study, we first set up the respective block diagrams of S-systems for module-based simulation. We then derive reasonable theorems to examine the stability of S-systems and find out what kinds of environmental situations will make systems stable. Three canonical systems are used to examine the results which are carried out in the Matlab/Simulink environments.

AbstractBentonite, which is envisaged as a promising engineered barrier material for the safe disposal of highly radioactive waste, was and is investigated in different large scale tests. The main focus was and is on the stability (or durability) of the bentonite. However, most countries concentrated on one or a few different bentonites only, regardless of the fact that bentonite performance in different applications is highly variable. Therefore, SKB (Svensk Kärnbränslehantering) set up the first large scale test which aimed at a direct comparison of different bentonites. This test was termed the ‘alternative buffer material test’ and considers eleven different clays which were either compacted (blocks) or put into cages to keep the material together. One so-called package consisted of thirty different blocks placed on top of each other. These blocks surrounded a heated iron tube 10 cm in diameter. Altogether three packages were installed in the underground test laboratory Äspö, Sweden. The first package was terminated 28 months after installation and the bentonite had been exposed for the maximum temperature (130°C) for about one year.Almost all geochemical and mineralogical alterations of the different bentonites (apart from exchangeable cations) were restricted to the contact between iron and bentonite. The increase of the Fe2O3 content was attributed to corrosion of the tube. However, the typical 7 or 14 Å smectite alteration product was not found. At the contact of one sample, siderite was precipitated. Some samples showed anhydrite and organic carbon accumulation and some showed dissolution of clinoptilolite and cristobalite. IR spectroscopy, XRD, and XRF data indicated the formation of trioctahedral minerals/domains in the case of some bentonites. Even more data has to be collected before unambiguous conclusions concerning both alteration mechanisms and bentonite differences can be drawn.

Development for whom, who get the benefits etc. became principal agenda in the present development discourses. It not limited to the development practitioners, politicians but also among the intellectuals. Major developmental projects which required larger areas of land such as dams projects, unable to provide proper rehabilitation to the effected people. The case of Hirakud Dam stands as an example of malady development in India. Numbers of big dams were constructed in the country, but, even till date no successful case of rehabilitation and resettlement comes to front. The questions deserve the right to ask the government and development practitioners, decision makers of the country. Who get the benefit? For whom you made such projects? If the common people (at least the affected people) should enjoy the benefit from the development project. The paper tends to highlight development scenario of the country with reference to big dams, and tries to draw conclusion from the Hirakud Dam project in Odisha, retain the position of longest earthen dam of world. The milieu of successful, failure of resettlement causes of the rebellion against the dam. The affected people have no got their compensation till today. On the other hand government of Indian planned more numbers of hydro-projects (Dams), industrial set up. Can, new projects escape from the malady?

Wave set-up is generally considered for the stability analysis of beaches, but not or not explicitly for the design of revetments. Based on large-scale model results with regular and irregular waves, it is shown in this paper that this is not justified. For this purpose, the wave set-up on a porous bonded revetment and the related internal set-up in the sand foundation below the revetment are analysed for different breaker types. The results particularly show that (i) considerable set-up values are obtained for almost all breaker types, (ii) a good correlation exists with the deep water wave length for both external and internal set-up and (iii) the internal set-up is significantly affected by the wave set-up on the slope. Empirical formulae for the prediction of the external and internal set-up are also proposed for both regular and irregular waves.

AbstractThe assembly of products is often supported by jigs. Especially for large dimensional products, jigs and fixtures are used to align the components and ensure the stability of the assembly until all parts are firmly mounted. This paper describes the development of mobile, modular and adaptive assembly jigs, which are designed to support ergonomic working in the production of high-lift systems for civil aircrafts. The jig supports the workers to adapt the position and orientation of the product to the current assembly operation. The fundamentals of the development are explained and the features of a concept, called assembly wheel, are presented. The assembly wheel consists of two or more robot arms on a circular seventh axis. The robot arms hold and position the components to be assembled so that all joining spots are freely accessible to the worker. The ergonomic benefits of the concept were examined in a study using a 3D model of the jig. A demonstrator on a scale of 1:2 was set up, with which real experiments with an adaptive jig can be conducted for evaluation.

New Evidence

In this paper the text of a new inscription from Ephesus will be presented and discussed. The fragmented stone on which it is written was brought by a workman to the excavation office in spring 1969. It is not known where exactly it was found, although D. Knibbe has suggested privately that it was originally set up in the Agora.Österreichisches Archäologisches Institut, Ephesus Inventory No. 3653. Fragment of a large slab of white marble, broken on top and at the bottom. The left margin is partly preserved, the right margin almost entirely. There are mouldings on both sides. The hollow in the form of a semicircle at the right margin originates in all probability from re-use of the stone.Height 75 cm. Width 68·5. Thickness 12·5. The height of the letters is 1·0, the distance between the lines 0·6 cm. The writing is in two columns which are separated from each other by a vertical scratch. This was made after the left column had already been engraved, as can be seen from the small detour in 1 19. Plate I. For the establishment of the text I have been able to use a large-scale photograph and the latex squeeze provided by the Austrian Archaeological Institute.

The Impact

ABSTRACTA method for the iterative set-up of optimum designs for crossbreeding experiments was used to study the robustness of designs to differences in the biological interpretation of two-locus epistatic interaction. Designs could be found which are efficient for the estimation of genetic models including, alternatively, seven different types of epistatic effects. Also, the design efficiency of a large-scale beef cattle crossbreeding experiment between Angus and Hereford cattle conducted at the Clay Center, Nebraska, and reported by Koch, Dickerson, Cundiff and Gregory (1985) was investigated and found to be high (proportionately 0·88 of the optimum). It was concluded that choice of the right genetic groups (i.e. types of crossbreds) seems to be more important for a good design than the exact number of observations allocated to each group.

Electroencephalogram Eeg

People experience events and form an impression of others in a way that is affected by social influence every day. In the present study, we designed a series of experiments centered on social influence to investigate people's bias in following others' opinions and its underlying neural predictors. Our results showed social conformity and proved that social influence-induced change can be predicted by the amount of electroencephalogram (EEG) variations when people view others' faces. This prediction effect is robust in the alpha-band over the right frontal and left occipital electrodes for negative influence. EEG variations can also predict the subsequent trust difference between negatively and positively influenced faces. Our findings suggest that higher EEG variations in the pre-influence task may serve as a predictor of high vulnerability to social influence. The present study provides a novel approach that considers both the stability of one's endogenous EEG and the variations in external task components to predict human social behaviors.
