THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

A fast-Fourier-transform method of topography and interferometry is proposed. By computer processing of a noncontour type of fringe pattern, automatic discrimination is achieved between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour-generation techniques. The method has advantages over moire topography and conventional fringe-contour interferometry in both accuracy and sensitivity. Unlike fringe-scanning techniques, the method is easy to apply because it uses no moving components.

TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulated intense research activities that focused on growth, modification, properties, and applications of these one-dimensional nanostructures. This review attempts to cover all these aspects, including underlying principles and key functional features of TiO(2), in a comprehensive way and also indicates potential future directions of the field.

Single-Phase induction motor is a major requirement for domestic applications as well as for industrial and commercial sectors. The popularity of SPIM is growing day by day due to its ruggedness, simplicity, inexpensiveness, low noise, ease of operation and reliability in size. To enhance the efficiency and torque of SPIM a lot of approaches have been proposed in past. The rotor geometry has an evident inspiration on the performance of singlephase induction motor. The rotor parameters play a crucial role in expansion of efficiency and torque developed by the motor. Researchers in the past have scrutinized the effects of rotor parameters on the performance of machine taking few parameters at a time to avoid complication of objective functions. The gap in the investigation & analysis of accumulative effect of all the rotor design parameters on the optimization has been shorted out by the advancement in the software techniques i.e. FEMM (Finite element method in magnetic), Maxwell etc. in which large number of parameters can be taken at a time in the simulation work. This paper presents the investigations & analysis of rotor geometry on the performance improvement in SPIM.

A Review on Influence of Rotor Geometry onthe Performance of Single-Phase Capacitor-Run Induction Motor

The selective determination of bio-active material is very important for medical point of view. Ion – selective electrode are the device used for the selective determination of target species in solutions because these device measured activity instead of molar concentration. In this work we have tested NaTFPB as potential carrier for the selective determination of azelastine in solutions. The membrane with composition of azelastine -tetrafluorophenyl borate (AZ – TFPB): DOP: PVC of 4%: 64%: 32% (w/w) works satisfactorily in the concentration range of 1.8 x 10−5 – 1.0 x 10−1 M, has a detection limit of 1.0 x 10−5 M and fast response time of 8 seconds. The proposed electrode can be used for a period of 3 weeks in a pH range of 2.5 – 6.0. The selectivity of membrane sensor towards target ions over some common interfering ions was calculated by MPM method.

The manufacturing process of flexible substrates develops the residual stress which leads to the birefringence. This birefringence can affect the polarization of the light passing through substrate along with the spectral changes in LCDs. We report that the effect of the birefringence of flexible substrate on the polarization state of the light passing through it. We observed that by aligning the optics axis of the PET film in a particular plane will not affect the light polarization of the backlight source.
