An Enduring Concept for Security Council Reform  [PDF]
Klaus Schlichtmann
Beijing Law Review (BLR) , 2011, DOI: 10.4236/blr.2011.22010
Abstract: UN Security Council reform has been lingering over the years, since it was first seriously considered in the 1990s, after the collapse of the Soviet Union. This paper argues that enlarging the Security Council by adding new permanent and non-permanent members, while many of the Charter provisions vital for the maintenance of international peace and security and disarmament are not in effect, would be counterproductive. Instead, the composition of the Council should be reshuffled and expanded by giving a seat to a prominent member of the Global South, i.e. India, and replacing the seats of France and Britain with a single European representation. While there would be no increase or change in the number of permanent and non-permanent members, the result will be a dramatic increase in the numbers of people represented by the Permanent Five, which then will, in effect, comprise half of the world’s population projected for 2012. The underlying logic is that increasing the number of permanent members (P5) would make the Security Council not only less effective, but also prevent the realization of a fundamental purpose of the United Nations, i.e. the transition from an armed to an unarmed peace. By maintaining the number 5, the effective operation of the consensus principle required for the maintenance of international peace and security during the transition is ensured. It is maintained that the changes proposed in this paper may be regarded as “purely procedural” under Article 27 paragraph 2 of the Charter. It will be seen, however, that to trigger the process of the transition, UN Member states (other than the P5, who bear responsibility under the Charter to guarantee safe passage during the transition) must begin, one by one, to delegate “Security Sovereignty” to the Council.
Analyse und Untersuchung der Quantisierungseffekte beim Goertzel-Filter
A. Tchegho,H. Gr?b,U. Schlichtmann,H. Mattes
Advances in Radio Science : Kleinheubacher Berichte , 2009,
Abstract: Digitale Filter k nnen in praktischen Anwendungen nur mit endlicher Wortbreite realisiert werden. Deshalb müssen Quantisierungseffekte verstanden werden, um die Eigenschaften und die Performanz der digitalen Filter geeignet einstellen zu k nnen. Die am st rksten beeinflussten Aspekte sind neben Frequenzgang, die Stabilit t und das Signal-Rausch-Verh ltnis. Zu geringe Wortbreiten führen zu drastischen Ver nderungen der Filtereigenschaften. Eine zu konservativ gew hlte Wortbreite hingegen, erh ht die Gr e und somit die Anzahl der Operationen des Filters unn tigerweise. Ziel dieses Beitrages ist es, für eine bestimmte Filterklasse optimale Wortbreiten zu finden, welche sowohl die Anzahl der Berechnungen und damit Operationen minimieren als auch sicherstellen, dass vorgegebene Toleranzbereiche für spezifizierte Filtereigenschaften eingehalten werden k nnen. Die Untersuchungen werden an einem Goertzel-Filter durchgeführt, welches aufgrund seiner effizienten Eigenschaften besonders für die spektrale Bewertung von Mixed-Signal Schaltungen und Systemen geeignet ist.
Ensembles and their modules as objects of cartosemiotic inquiry
Hansgeorg Schlichtmann
Meta-Carto-Semiotics , 2010,
Abstract: The structured set of signs in a map face -- here called map-face aggregate or MFA -- and the associated marginal notes make up an ensemble of modules or components (modular ensemble). Such ensembles are recognized where groups of entries are intuitively viewed as complex units, which includes the case that entries are consulted jointly and thus are involved in the same process of sign reception. Modular ensembles are amenable to semiotic study, just as are written or pictorial stories. Four kinds (one of them mentioned above) are discussed in detail, two involving single MFAs, the other two being assemblages of maps, such as atlases. In terms of their internal structure, two types are recognized: the combinate (or grouping), in which modules are directly linked by combinatorial relations (example above), and the cumulate (or collection (of documents)), in which modules are indirectly related through some conceptual commonality (example: series of geological maps). The discussion then turns to basic points concerning modular ensembles (identification of a module, internal organization of an ensemble, and characteristics which establish an ensemble as a unit) and further to a few general semiotic concepts as they relate to the present research. Since this paper originated as a reaction to several of A. Wolodtschenko’s recent publications, it concludes with comments on some of his arguments which pertain to modular ensembles.
Peripheral meaning in maps: The example of ideology
Hansgeorg Schlichtmann
Meta-Carto-Semiotics , 2008,
Abstract: The basic function of a map is the intentional conveyance of information about a territory. Sign contents relating to other domains are peripheral to the said information and are therefore collectively called peripheral meaning. One kind of peripheral meaning, i.e., ideology, is the subject matter of the present paper. At this place, "ideology" is a short term for beliefs about the socio-political component of the world. On the basis of observations gleaned from the cartographic literature, an attempt is made to place ideology into a semiotic frame. An ideological meaning component is considered a connotation which is often associated not with a single type of entries but a class of such types. Finally, the retrieval of ideological connotations in map interpretation is sketched.
Emulated ASIC Power and Temperature Monitor System for FPGA Prototyping of an Invasive MPSoC Computing Architecture
Elisabeth Glocker,Qingqing Chen,Asheque M. Zaidi,Ulf Schlichtmann,Doris Schmitt-Landsiedel
Computer Science , 2014,
Abstract: In this contribution the emulation of an ASIC temperature and power monitoring system (TPMon) for FPGA prototyping is presented and tested to control processor temperatures under different control targets and operating strategies. The approach for emulating the power monitor is based on an instruction-level energy model. For emulating the temperature monitor, a thermal RC model is used. The monitoring system supplies an invasive MPSoC computing architecture with hardware status information (power and temperature data of the processors within the system). These data are required for resource-aware load distribution. As a proof of concept different operating strategies and control targets were evaluated for a 2-tile invasive MPSoC computing system.

Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.610083

The main purpose of this study is to obtain the water infiltration parameters of the soils of Michael Okpara University of Agriculture, Umudike. This could be used in simulating infiltration for these soils when designing irrigation projects, thereby saving time and cost of field measurement. Field measurements of infiltration were first made using a double ring infiltrometer. The test lasted for 180 mins in each location. Infiltration values ranged from 0.03 cm/min to 0.1 cm/min. The highest value was obtained in the Forest Block. Kostiakov’s infiltration model was then applied on the field data in order to determine the soils’ infiltration parameters and equations. The model empirical constants or parameters obtained were “m” and “n”. For “m” the values were: 0.53 for the soil of Forest Block, 0.42 for Poultry block, 0.50 for P.G. block, 0.41 for the soils of Staff School and Guest House. The corresponding “n” values were: 1.37, 1.12, 0.37, 1.79, and 1.38. Infiltration equations: 0.4It1.38, 0.4lt1.79, 0.42t1.12, and 0.53t1.37 were determined for the locations. These were used to simulate data which were evaluated by comparing them with the field data. The two data sets showed closed relationships. This implied that the model could be used to simulate water infiltration during irrigation projects in the farms of Michael Okpara University of Agriculture, Umudike.

Effects of Kolaviron, the Major Constituent of Garcinia kola, on the Histology of the Hypothalamus, Pituitary, and Testes Using Adult Male Wistar Rats as a Model Organism  [PDF]

Forensic Medicine and Anatomy Research (FMAR) , 2014, DOI: 10.4236/fmar.2014.23014
Abstract: This study determined the effects of kolaviron on the histology of organs of the hypothalamic-pi- tuitary-gonadal axis, mainly the hypothalamus, pituitary and testis. The aim was to ascertain if its consumption has deleterious effects on these organs. Thirty six adult Wistar rats divided into six groups of six animals each were used and kolaviron administered at 100, 200, 400 and 800 mg/kg body weight. The results showed that gross cellular depletion and desquamation of cells of testis significantly reduced number of cells in the hypothalamus and pituitary (P < 0.05). It significantly reduced the relative brain weight (P < 0.05). These findings suggest that kolaviron can alter the histology of the axis which may impair its reproductive function.
A Multi-Objective Obnoxious Facility Location Modelon a Plane  [PDF]
U. K. Bhattacharya
American Journal of Operations Research (AJOR) , 2011, DOI: 10.4236/ajor.2011.12006
Abstract: In this paper a Vertex Covering Obnoxious Facility Location model on a Plane has been designed with a combination of three interacting criteria as follows: 1) Minimize the overall importance of the various exist-ing facility points; 2) Maximize the minimum distance from the facility to be located to the existing facility points; 3) Maximize the number of existing facility points covered. Area restriction concept has been incor-porated so that the facility to be located should be within certain restricted area. The model developed here is a class of maximal covering problem, that is covering maximum number of points where the facility is within the upper bounds of the corresponding mth feasible region Two types of compromise solution methods have been designed to get a satisfactory solution of the multi-objective problem. A transformed non- linear programming algorithm has been designed for the proposed non-linear model. Rectilinear dis-tance norm has been considered as the distance measure as it is more appropriate to various realistic situa-tions. A numerical example has been presented to illustrate the solution algorithm.

World Journal of AIDS (WJA) , 2011, DOI: 10.4236/wja.2011.14019
Abstract: We attempted to study the role of HLA HLA-A, B, DRB1 and DQB1 in HIV-1 patient’s co infected with pulmonary tuberculosis (PTB). A total of 102 HIV-1 + patients co-infected with pulmonary tuberculosis and 200 healthy controls were included in HLA analysis. HLA-A*, HLA-B* HLA-DRB1* and DQB1* typing was done molecularly by PCR- SSOP (Polymerase Chain reaction-Sequence Specific Oligonucleotide Probing) method using kit (Dynal Kit – Invitrogen). The frequencies of the HLA-A, B HLA-DRB,1 and DQB1 alleles were determined using standard software. The HLA alleles identified among HIV + ve/PTB + ve co-infected patients as compared with healthy controls showed a significantly increased frequency of HLA-B*08:01:01 in HIV + ve/PTB + ve co-infected patients when compared with healthy controls (p = 0.011, OR 3.335, 95% CI 1.35-8.18), Likewise HLA-DQB1*03:01:03 was significantly increased in HIV + ve/PTB + ve co-infected patients as against healthy controls (p < 0.0001, OR 107.5, 95% CI 6.195 - 1865.3). Similarly HLA-DQB*06:01:02 allele frequency was observed in HIV + ve/PTB + ve co-infected patients as against healthy controls (p = 0.003, OR 4.808, 95% CI 1.72-13.39), HLA-DQB1*03:01:01 (p = 0.045, OR 0.219, 95% CI 0.051 - 0.940), HLA-DQB1*06:01:01:01 (p = 0.012, OR 0.334, 95% CI 0.145 - 0.770), alleles in HIV + ve/PTB + ve co-infected patients when compared with healthy controls. We can be concluded that different HLA alleles may render susceptibility or protection to in different ethnic population.
Unsteady Incompressible Flow of a Generalised Oldroyed-B Fluid between Two Infinite Parallel Plates  [PDF]
D. Bose, U. Basu
World Journal of Mechanics (WJM) , 2013, DOI: 10.4236/wjm.2013.32012

This paper presents a study of visco-elastic flow of an incompressible generalized Oldroyd-B fluid between two infinite parallel plates in which the constitutive equation involves fractional order time derivative. The solutions of field equations are being obtained for the motion of the said fluid between two parallel plates where the lower plate starts to move with steady velocity and the upper plate remains fixed in the first problem and the upper plate oscillates with constant frequency and the other being at rest in the second problem. The exact solutions for the velocity field are obtained by using the Laplace transform and finite Fourier Sine transform technique in terms of Mittag Leffler and generalised functions. The analytical expression for the velocity fields are derived and the effect of fractional parameters upon the velocity field is depicted graphically.
