From the 'Rescue of the Nation State' to the Emergence of European Spaces. EUIJ-Kansai Workshop on "New Research Horizons of the History of European Integration", May 10, 2008, Toyonaka (Osaka)
No full textThe aim of this paper is to make some contribution to the discussion on the future direction of the historical research on the European integration processes. What I intend to do here is, broadly, to link the contemporary European studies to the Historical studies, and concretely, to emphasise the transnational dimension of European integration. This exercise should be read as presenting my "wish list" to the Integration Historians

No full textAmiya Kumar Bagchi, an eminent economist of the modern
Cambridge tradition, has produced a timely treatise, in a condensed
form, on the development problems of the Third World countries. The
author's general thesis is that economic development in the developing
societies necessarily requires a radical transformation in the economic,
social and political structures. As economic development is actually a
social process, economic growth should not be narrowly defined as the
growth of the stock of rich capitalists. Neither can their savings be
equated to capital formation whose impact on income will presumably
'trickle down' to the working classes. Economic growth strategies must
not aim at creating rich elites, because, according to the author,
"maximizing the surplus in the hands of the rich in the Third World is
not, however, necessarily a way of maximizing the rate of
growth"
Seismic Response of Partially Filled Sloped Bottom Container and Tuned Liquid Damper for Vibration Control
No full textThe oscillation of the unrestrained free liquid surface in a partially filled container due to some external excitation is termed as sloshing. It comprises a wide range of problems in many fields of engineering such as aerospace, civil, marine, nuclear and so on. In the field of civil engineering, a considerable understanding of sloshing behavior in a water retaining structure is needed. This dissertation makes an honest attempt to study the response of ground supported sloped bottom container and its application as a tuned liquid damper to control the uncalled vibration of the structure.
In this thesis, the finite element method in two dimensional space is adopted where the liquid domain is discretized as a combination of three node triangular and four node quadrilateral elements. A parametric study is carried out with different slope angle and bottom length on ground supported sloped bottom tanks. The numerical study is dedicated to investigate the liquid response in sloped bottom tanks under earthquake ground motion of various frequency contents. The model is efficient in determining both the impulsive and convective responses of liquid in container. The dynamic parameters of sloshing are manifested in terms of base shear force, slosh displacement and pressure distribution along the walls of the containers. It is observed that the geometry and size of the container plays a significant role in sloshing behavior of partially filled container. Also, the frequency content of earthquake ground motion is found to affect the sloshing characteristics significantly.
Further, the study is extended to investigate the effectiveness of sloped bottom TLD in controlling the vibration of structure. A TLD-structure interaction model is developed for the shear building structures subjected to horizontal harmonic and earthquake ground motions. A parametric study is carried out to determine the performance of sloped bottom TLD in reducing the undesired vibration of the structure. The experimental investigation is undertaken in a TLD-structure model, on a unidirectional shake table capable of producing horizontal harmonic excitation. The efficiency of different angle sloped bottom TLD and flat bottom TLD in mitigating the structural vibration is determined. Studies reveal that sloped bottom TLD efficiently controlled the unwanted vibration of structure with less amount of water than that of rectangular TLD.
Lastly, Adaptive Neuro Fuzzy Inference System (ANFIS), a smart hybrid soft computing technique is implemented to predict the dynamic properties of sloshing, so that the expenditure associated with experiments can be reduced. The numerically simulated results are used as input-output data set. ANFIS is found to be a promising soft computing tool in predicting the earthquake magnitude and sloshing response in sloped bottom containers. Subtractive clustering algorithm is found efficient to predict the earthquake magnitude and hydrodynamic base shear force in very small amount of time
Sloshing response of partially filled rectangular tank under periodic horizontal ground motion.
No full textThe event caused due to the movement of the unrestricted free surface liquid in container due to any external excitation is known as sloshing. The problem of liquid sloshing phenomenon in stationary or in moving container is a great matter of concern for many researchers and engineers. The containers may range from a cup of milk, ponds, and lakes to fuel tanks of launching vehicles and cargo ships carrying variety of liquids such as oil, liquefied natural gas, and chemical fluids. As a result of sloshing there is spillage of liquid from the containers and it causes structural instability and structural damage. Due to these reasons, liquid retaining structures which are special in construction and in function from an engineering point of view must be constructed well to be resistant against oscillation of the liquid due to external excitations. The amount of liquid participating in the sloshing motion depends on the shape of tank, the liquid depth, internal objects, if any, orientation, duration, amplitude, and frequency contents of external excitations. This present study focuses on the forced vibration analysis of partially filled two-dimensional rigid rectangular tank numerically. A Finite element (FE) code in two dimensions is developed to understand the behavior of sloshing. This method is competent enough of evaluating both impulsive and convective response of tank-liquid system in terms of base shear and hydrodynamic pressure distribution along the walls of the containers

No full textHanes observed that equilibria in phosphorylase systems were unaffected by alterations in the concentrations of starch. He inferred therefrom that starch solutions might contain some component in a highly disaggregated condition which may be chemically active and this component was maintained in a state of saturation. Since direct chemical analysis is not possible, we have tried to approach the problem of determining the nature of this component from theoretical side based on a new theory of phoephorylase action, recently put forward by the author
Seismic resilience enhancement of MDOF systems utilizing a hybrid TMD-TLD
No full textThis paper proposes a novel hybrid tuned mass damper (TMD) and tuned liquid damper (TLD) system (TMD + TLD) for vibration control of multi-degree of freedom structures under seismic excitations. The proposed system is introduced using equations of motions of a five-degree of freedom structure which is modeled as a shear-type with a lateral degree of freedom at each floor under harmonic and earthquake excitations. The proposed hybrid TMD + TLD system is introduced to the building structure in the model. Several case studies are investigated to evaluate the performance of the proposed system. In the first case, both TMD and TLD are tuned to the first frequency of the structure, and the TMD is fixed to the top floor, and the TLD is fitted to the fourth floor of the primary structure. In the second case, the TMD is tuned to the first frequency of the structure, whereas the TLD is tuned to the second frequency of the structure. All the cases are investigated under harmonic force and real earthquake ground motions. The earthquakes selected in this study are classified as low, intermediate, and high-frequency content earthquakes. Results indicated that with comparatively less mass ratio, the earthquake-induced structural vibration is successfully suppressed when the TMD is tuned to the 1st frequency, and the TLD is tuned to the 2nd frequency of the structure. The focus of the investigation is to develop a practical framework to demonstrate the efficiency of such a hybrid damper

No full textAbstract: We consider the broadcasting problem in sensor networks where the nodes have no prior knowledge of their neighbourhood. We describe several Area-based Beaconless Broadcasting Algorithms (ABBAs). In 2D, on receiving the packet (together with geographic coordinates of the sender), each node calculates the ratio P of its perimeter, along the circle of transmission radius, that is not covered by this and previous transmissions of the same packet. The node then sets or updates its timeout to be inversely proportional to P. If the perimeter becomes fully covered, the node cancels retransmissions. Otherwise, it retransmits at the end of the timeout interval. The protocol is reliable, that is, all nodes, connected to the source, are guaranteed to receive the packet, assuming an ideal MAC layer. We also describe three 3D-ABBAs, one of them being reliable. These three protocols are based on covering three projections, covering particular points on intersection circles and covering intersection points of three spheres. Our protocols are the first reliable broadcasting protocols, other than blind flooding
