Psychic systems and metaphysical machines: experiencing behavioural prediction with neural networks
Authors: Kazemzadeh Max B 
Published: December 2010

We are living in a time of meta-organics and post-biology, where we perceive everything in our world as customizable and changeable. Modelling biology within a technological context allows us to investigate GEO-volutionary alternatives/alterations to our original natural systems, where
augmentation and transmutation become standards in search of overall betterment (Genetically Engineered Organics). Our expectations for technology exceeds ubiquitous access and functional perfection and enters the world of technoetics, where our present hyper-functional, immersively multi-apped,
borderline-prosthetic, global village devices fail to satiate our desires to be synaptically surpassed. Most real-time interactive behavioural systems in art utilize two and three dimensions. Artificial neural networks and prediction (Latin: from pr- before plus dicere to say)
systems give rise to experimentation within the third-plus-one (3+1) dimension of the spacetime continuum.
Spacetime in accordance with string theory requires the where and when to describe something in existence, rather than mere points in space. It explains the workings of the universe
from both super-galactic and subatomic levels. Physical cosmology studies the motions of the celestial bodies in relation to the first cause (ie. primum movens) or the source of all-being.
In book 12 of Metaphysics, Aristotle spoke of something which moves without (itself) being
moved (by anything), and referred to being as motion. In quantum mechanics, a particle is described by a wave. Physiognomy is an evolving area of psychological research that describes a direct correlation between human gesture (or movement) and thought. Early twentieth-century Persian philosopher
Abdul-Baha mentioned that the reality of man is his thought, not his material body. Prediction systems apply models of the mind, or artificial neural networks and machine learning strategies, to use the recorded past with the present to anticipate the future. This article investigates existing
human and artificial psychic systems in hopes of identifying tools necessary in building a gesture prediction system. The relationship of intent to gesture and whether intent can be perceived without the evidence of gesture are two factors that must be tested.
Searching for love impossible
Authors: Ryu Semi 
Published: December 2010

We live in layers of mixed realities with continuous conflicts, negotiation and becoming. I find it interesting to look at our situation as a continuous struggle in the fusion of virtual/actual presences, and machine/human. However, we seem to be far from understanding these relationships.
Maybe the problem lies in the questions themselves, promoting unidirectional preconceptions. By reversing the questions, we might be able to identify something that has been missing in previous discussions:
Can we talk about disconnection to further discuss connection?
Can we talk about
distancing to further discuss the process of becoming?
Can we talk about love impossible, to further discuss love?
This paradoxical journey would maintain us in the continuum of struggle and massive doubts, and encounter deep aspects of human being. In this article, I examine the Korean
cultural psyche called han in the context of a paradoxical state of consciousness and the story of love impossible, and argue that han is a driving force of transformative ritual in human consciousness. Beyond cultural boundaries, this article also positions han in a microscopic
view of contemporary life. han underlies paradoxical human relationships with objects, and with my virtual puppets, in the context of distance, disconnection and love impossible.
Trenchless Case History—University of Denver’s Use of High-Performance Restrained-Joint Water Distribution Pipe
Authors: Gross Steven B. , Tippets Brenden 
Published: December 2010

Abstract
The benefits of trenchless technology are well understood by all in our industry—more cost-effective and less disruptive to streets, driveways, and landscaping. However, what is often less clear to many engineers and city officials faced with a wide selection of materials and processes is just what type of pipe is best suited for a particular trenchless application. This paper will present the engineering considerations involved in selecting thermoplastic water distribution pipe for directional drilling projects, focusing on assembly considerations, structural and flow performance, pressure-handling capacity, joint integrity, and compatibility with existing systems. These concepts are illustrated by the experiences at the University of Denver, where trenchless technology was successfully utilized on an irrigation system in an area where conventional pipe installation techniques were determined to be unsatisfactory.

ObjectiveIn aging populations, poor handgrip strength has been associated with physical disability and mortality. IGF1 is an important mediator of muscle growth and regeneration affecting muscle function. We studied the relationship between circulating levels of IGF1, its binding protein 3 (IGFBP3), and handgrip strength and physical performance in middle-aged- and oldest-old subjects.DesignCross-sectional analysis in two different cohorts composed of middle-aged- (n=672, mean 63.9±6.7 years) and oldest-old subjects (n=272, all 89 years).MethodsHandgrip strength, functional performance and ability, and serum levels of IGF1 and IGFBP3 were measured in all subjects and analyzed by linear regression for men and women separately.ResultsIGF1 and IGFBP3 levels declined with chronological age and were positively associated with handgrip strength in middle-aged- and oldest-old women (both, P<0.05), but not in men of either age group. Furthermore, higher serum levels of IGF1 were associated with slower walking speed in oldest-old men (P=0.012), and serum levels of IGFBP3 were positively associated with activities of daily living in the oldest-old women (P=0.002).ConclusionThe significant relationship between IGF1 levels and muscle strength found in women but not in men suggests a gender-specific influence of IGF1 on muscle strength. Further studies are necessary to test the relationship with physical performance.
Coming of Age: Breast Cancer in Seniors
Authors: Muss Hyman B. 
Published: December 2010

Abstract
In the U.S., cancer is a disease of aging. The average 65-year-old patient has an anticipated life expectancy of 20 years, and clinicians should take this into account when making breast cancer management decisions. However, older breast cancer patients can present with wide variations in health status, and treatment in older patients should therefore include a careful evaluation of comorbidities, physical function, polypharmacy, and other issues that could potentially impact a patient's ability to undergo chemotherapy without excessive risk. Evaluation tools are under development, including potential molecular markers, to identify which older patients are the best candidates for chemotherapy, as well as those more susceptible to actually developing cancer. Standard chemotherapy regimens are just as effective in older patients as they are in the younger population, and can substantially prolong life expectancy when used in the right patients. This article discusses breast cancer in seniors, including the epidemiology of breast cancer in these patients, the potential impact of comorbidities, and effective adjuvant therapy in selected older patients.
Equicrestal and Subcrestal Dental Implants: A Histologic and Histomorphometric Evaluation of Nine Retrieved Human Implants

Published: December 2010

Background: Stability of peri‐implant crestal bone plays a relevant role relative to the presence or absence of interdental papilla. Several factors can contribute to the crestal bone resorption observed around two‐piece implants, such as the presence of a microgap at the level of the implant–abutment junction, the type of connection between implant and prosthetic components, the implant positioning relative to the alveolar crest, and the interimplant distance. Subcrestal positioning of dental implants has been proposed to decrease the risk of exposure of the metal of the top of the implant or of the abutment margin, and to get enough space in a vertical dimension to create a harmoniously esthetic emergence profile.Methods: The present retrospective histologic study was performed to evaluate dental implants retrieved from human jaws that had been inserted in an equicrestal or subcrestal position. A total of nine implants were evaluated: five of these had been inserted in an equicrestal position, whereas the other four had been positioned subcrestally (1 to 3 mm).Results: In all subcrestally placed implants, preexisting and newly formed bone was found over the implant shoulder. In the equicrestal implants, crestal bone resorption (0.5 to 1.5 mm) was present around all implants.Conclusion: The subcrestal position of the implants resulted in bone located above the implant shoulder.

Individual differences in wild (WWCPS) rat — manifested in the exploration boxThirty nine WWCPS rats were tested in the exploration box throughout fifteen sessions. Factor analysis was run to extract the main dimensions describing rat behavior. Two factors were extracted, confirming the validity of the concept of two dimensional structure of individual differences in rats. Hierarchical cluster analysis run on factor scores showed that only three out of a possible four types of factor combinations are actually present within observed group of animals. In terms of individual differences structure, the study provide support for the view that laboratory rats are still rats.
Triplet superfluidity in neutron matter with Skyrme forces at subnuclear and supranuclear densities in a strong magnetic field
Authors: Tarasov Alexander 
Published: December 2010

Abstract
Within a generalized non-relativistic Fermi-liquid approach we have found general analytical formulae for phase-transition temperatures T
c,1(n, H) and T
c,2(n, H) (which are nonlinear functions of density, n, and linear of magnetic field, H) for phase transitions in spatially uniform, dense, pure neutron matter from normal to superfluid states with spin-triplet p-wave pairing (similar to anisotropic superfluid phases 3He - A1 and 3He - A2) in steady and homogeneous sufficiently strong magnetic field (but |µn|H ≪ E
c < ɛ
F(n), where µn is the magnetic dipole moment of a neutron, E
c is the cutoff energy and ɛ
F(n)is the Fermi energy in neutron matter). General formulae for T
c,1,2(n,H) are valid for arbitrary parameterization of the effective Skyrme forces in neutron matter. We have used for definiteness the so-called SLy2, Gs and RATP parameterizations of the Skyrme forces with different exponents in their power dependence on density n (at sub- and supranuclear densities) from the interval 0.7 n
0 ≲ n < n
c(Skyrme)< 2 n
0, where n
0 =0.17 fm−3 is the nuclear density and n
c(Skyrme)is the the critical density of the ferromagnetic instability in superfluid neutron matter. These phase transitions might exist in the liquid outer core of magnetized neutron stars.

The paper focuses on the giant magnetoresistance effect in these materials, and their potential usefulness for spintronic applications. As examples, the following devices are shortly discussed: GrNs in the ballistic transport regime, a CNT-based Schottky-barrier field effect transistor (CNT SB-FET), as well as CNT quantum dots in the Coulomb blockade limit.
Identification of the heat transfer coefficient in phase change problems
Authors: Słota Damian 
Published: December 2010

Identification of the heat transfer coefficient in phase change problemsIn this paper, an algorithm will be presented that enables solving the two-phase inverse Stefan problem, where the additional information consists of temperature measurements in selected points of the solid phase. The problem consists in the reconstruction of the function describing the heat transfer coefficient, so that the temperature in the given points of the solid phase would differ as little as possible from the predefined values. The featured examples of calculations show a very good approximation of the exact solution and stability of the algorithm.
Application of evaluationary approach to thermo-mechanical optimization of gas turbine airfoil cooling configuration
Authors: Nowak Grzegorz 
Published: December 2010

Application of evaluationary approach to thermo-mechanical optimization of gas turbine airfoil cooling configurationCooling of the hot gas path components plays a key role in modern gas turbines. It allows, due to efficiency reasons, to operate the machines with temperature exceeding components' melting point. The cooling system however brings about some disadvantages as well. If so, we need to enforce the positive effects of cooling and diminish the drawbacks, which influence the reliability of components and the whole machine. To solve such a task we have to perform an optimization which makes it possible to reach the desired goal. The task is approached in the 3D configuration. The search process is performed by means of the evolutionary approach with floatingpoint representation of design variables. Each cooling structure candidate is evaluated on the basis of thermo-mechanical FEM computations done with Ansys via automatically generated script file. These computations are parallelized. The results are compared with the reference case which is the C3X airfoil and they show a potential stored in the cooling system. Appropriate passage distribution makes it possible to improve the operation condition for highly loaded components. Application of evolutionary approach, although most suitable for such problems, is time consuming, so more advanced approach (Conjugate Heat Transfer) requires huge computational power. The analysis is based on original procedure which involves optimization of size and location of internal cooling passages of cylindrical shape within the airfoil. All the channels can freely move within the airfoil cross section and also their number can change. Such a procedure is original.
Mathematical modelling of heat transfer in liquid flat-plate solar collector tubes
Authors: Zima Wiesław , Dziewa Piotr 
Published: December 2010

Mathematical modelling of heat transfer in liquid flat-plate solar collector tubesThe paper presents a one-dimensional mathematical model for simulating the transient processes which occur in the liquid flat-plate solar collector tubes. The proposed method considers the model of collector tube as one with distributed parameters. In the suggested method one tube of the collector is taken into consideration. In this model the boundary conditions can be time-dependent. The proposed model is based on solving the equation describing the energy conservation on the fluid side. The temperature of the collector tube wall is determined from the equation of transient heat conduction. The derived differential equations are solved using the implicit finite difference method of iterative character. All thermo-physical properties of the operating fluid and the material of the tube wall can be computed in real time. The time-spatial heat transfer coefficient at the working fluid side can be also computed on-line. The proposed model is suitable for collectors working in a parallel or serpentine tube arrangement. As an illustration of accuracy and effectiveness of the suggested method the computational verification was carried out. It consists in comparing the results found using the presented method with results of available analytic solutions for transient operating conditions. Two numerical analyses were performed: for the tube with temperature step function of the fluid at the inlet and for the tube with heat flux step function on the outer surface. In both cases the conformity of results was very good. It should be noted, that in real conditions such rapid changes of the fluid temperature and the heat flux of solar radiation, as it was assumed in the presented computational verification, do not occur. The paper presents the first part of the study, which aim is to develop a mathematical model for simulating the transient processes which occur in liquid flat-plate solar collectors. The experimental verification of the method is a second part of the study and is not presented in this paper. In order to perform this verification, the mathematical model would be completed with additional energy conservation equations. The experimental verification will be carry out in the close future.

Absorption and adsorption chillers applied to air conditioning systemsThis work presents an application possibility of sorption refrigerators driven by low temperature fluid for air conditioning of buildings. Thermodynamic models were formulated and absorption LiBr-water chiller with 10 kW cooling power as well as adsorption chiller with silica gel bed were investigated. Both of them are using water for desorption process with temperatureTdes= 80 °C. Coefficient of performance (COP) for both cooling cycles was analyzed in the same conditions of the driving heat source, cooling waterTc= 25 °C and temperature in evaporatorTevap= 5 °C. In this study, the computer software EES was used to investigate the performance of absorption heat pump system and its behaviour in configuration with geothermal heat source.

Authors: Mika Łukasz 
Published: December 2010

Loss coefficients of ice slurry in sudden pipe contractionsIn this paper, flow systems which are commonly used in fittings elements such as contractions in ice slurry pipelines, are experimentally investigated. In the study reported in this paper, the consideration was given to the specific features of the ice slurry flow in which the flow behaviour depends mainly on the volume fraction of solid particles. The results of the experimental studies on the flow resistance, presented herein, enabled to determine the loss coefficient during the ice slurry flow through the sudden pipe contraction. The mass fraction of solid particles in the slurry ranged from 5 to 30%. The experimental studies were conducted on a few variants of the most common contractions of copper pipes: 28/22 mm, 28/18 mm, 28/15 mm, 22/18 mm, 22/15 mm and 18/15 mm. The recommended (with respect to minimal flow resistance) range of the Reynolds number (Re about 3000-4000) for the ice slurry flow through sudden contractions was presented in this paper.
Fluid flow consideration in fin-tube heat exchanger optimization
Authors: Wais Piotr 
Published: December 2010

Fluid flow consideration in fin-tube heat exchanger optimizationThe optimization of finned tube heat exchanger is presented focusing on different fluid velocities and the consideration of aerodynamic configuration of the fin. It is reasonable to expect an influence of fin profile on the fluid streamline direction. In the cross-flow heat exchanger, the air streams are not heated and cooled evenly. The fin and tube geometry affects the flow direction and influences temperature changes. The heat transfer conditions are modified by changing the distribution of fluid mass flow. The fin profile impact also depends on the air velocity value. Three-dimensional models are developed to find heat transfer characteristics between a finned tube and the air for different air velocities and fin shapes. Mass flow weighted average temperatures of air volume flow rate are calculated in the outlet section and compared for different fin/tube shapes in order to optimize heat transfer between the fin material and air during the air flow in the cross flow heat exchanger.
The influence of external cooling system on the performance of supercritical steam turbine cycles
Authors: Kosman Wojciech 
Published: December 2010

The influence of external cooling system on the performance of supercritical steam turbine cyclesThe problem presented in this paper refers to the concepts applied to the design of supercritical steam turbines. The issue under the investigation is the presence of a cooling system. Cooling systems aim to protect the main components of the turbines against overheating. However the cooling flows mix with the main flow and modify the expansion line in the steam path. This affects the expansion process in the turbine and changes the performance when compared to the uncooled turbine. The analysis described here investigates the range of the influence of the cooling system on the turbine cycle. This influence is measured mainly through the change of the power generation efficiency. The paper explains the approach towards the assessment of the cooling effects and presents results of the modeling for three supercritical steam cycles.

Thermodynamic analysis of a new conception of supplementary firing in a combined cycle
The paper analyzes a new concept of integration of combined cycle with the installation of supplementary firing. The whole system was enclosed by thermodynamic analysis, which consists of a gas-steam unit with triple-pressure heat recovery steam generator. The system uses a determined model of the gas turbine and the assumptions relating to the construction features of steam-water part were made. The proposed conception involves building of supplementary firing installation only on part of the exhaust stream leaving the gas turbine. In the proposed solution superheater was divided into two sections, one of which was located on the exhaust gases leaving the installation of supplementary firing. The paper presents the results of the analyses of which the main aim was to demonstrate the superiority of the new thermodynamic concept of the supplementary firing over the classical one. For this purpose a model of a system was built, in which it was possible to carry out simulations of the gradual transition from a classically understood supplementary firing to the supplementary firing completely modified. For building of a model the GateCycle™ software was used.
