Effectiveness Of Training Programs For Graduate Engineers, V.C. Rajashekar

Theses

This thesis represents an investigation of effectiveness as a result of engineering training. The basic elements of effectiveness and its learning process are explained and said that the effectiveness could be learnt and improved.

The term training, is basically the process of education and training. But training cannot be performed as an individual, but is performed as a group. Therefore training a group with having so many individuals needs careful consideration in designing a training program.

In order to get the broadest possible picture of current thinking and current activity in the area of company training programs for graduate engineers, …

The Effect Of Ultrasonic Vibration On Mass Transfer In A Packed Column, Joseph Walter Stanecki

Theses

The object of this research was to investigate the possibility of using externally supplied ultrasonic vibration to surface of a packed distillation column operating at total reflux to improve the separation. The apparatus used for this experimentation consisted of a 2 inch ID Pyrex column having three pairs of ultrasonic transducers epoxied equidistance along the external surface of the column. Each pair of transducers was driven separately by a 50 watt amplifier! power supply and a sine/square wave generator.

There were three types of binary mixtures covered during experimentation: minimum boiling azeotropes, maximum boiling azeotropes and full range mixtures. In …

Design And Construction Of A Standard Planetary Microfilming Camera Target Array (Pmta), Bruno Glavich, Richard Johnson

Theses

After researching the current applications, problems, and evaluation techniques of planetary microfilming systems, the authors designed and constructed a standard Planetary Microfilming camera Target Array (PMTA) that essentially satisfied three criteria, i.e. 1) inexpensive to produce, 2) simple to use, and 3) satisfies testing criteria for both microfilming equipment manufacture and user. Ten evaluation parameters were incorporated in two targets PMTA-I and PMTA-II. PMTA-I includes tests for 1) resolution, 2) readability of printed matter, 3) reduction ratio, 4) exposure and processing, 5) full field visual distortion, and finally 6) corner visual distortion. PMTA-II was designed to evaluate, 7) quatitative distortion, …

Optical Measurement Techniques For Blanket Release Characteristics On Web Presses, Joseph Griggs, Ronald Sandford

Theses

Offset printing involves the transfer of ink from the image areas of the printing plate to the paper through an intermediate blanket. The blanket is usually composed of synthetic fiber materials (e.g. nylon). Blanket-paper-ink characteristics contribute to limits of printing quality and mechanical press operation. Paper and blanket physical surface characteristics and also ink tackiness contribute to adhesion between the paper and blanket. If the adhesion is sufficiently large, the force required to separate the paper from the blanket may cause deterioration of print quality or press operational problems. Deterioration of the printed quality may include picking of coating from …

Tone Reproduction Of Small-Scale Images Using Lithographic Film Under Infectious And Noninfectious Developmental Conditions, Julian Lopez

Theses

The tone reproduction curve of small-scale images on KODALITH film developed with KODALITH Super Developer were obtained by microdensitometry using a sinusoidal target of 64 percent modulation as a sensitometric tablet to produce images at spatial frequencies corresponding to screen rulings of 9 to 375 lines/inch. A similar series of exposures was processed with addition of sulfite to the developer to give essentially noninfectious development. Speed and contrast with KODALITH developer increased with spatial frequency; speed increased continuously by a small factor and contrast passed through a maximum (80 percent greater than for large area image) at a spatial frequency …

An Investigation Of The Aesthetic Quality Of Gloss As Produced By Overprint Varnishing, John Bechtel

Theses

The undertaking of this investigation was to question the aesthetic significance of overprint varnish. To do this a statistical investigation was developed to answer the question: "When the protection factor of overprint varnishing is of little or no significance, does overprint varnishing of the finished product add an element of aesthetic quality sufficient to justify the outlay of additional funds?" The philosophy of the investigation revolved around the investigative sample distinguishing the overprint varnishing process as a significant aesthestic enhancement process. To do this a sample of 15 sets of magazine quality reproductions, all printed under the same conditions, were …

A New Technique For Steady State And Transient Analyses Of Incompressible Flow Networks, George V. Catanzaro

Theses

A new technique for the calculation of the transient or the steady-state mass flow rate and pressure distribution in incompressible flow networks is presented. Employing the matrix method of network analysis, the nodal continuity and branch momentum equations are solved simultaneously to obtain explicit relations giving the unknown nodal pressures and branch mass flow rates. In this manner, the transient or the steady-state behavior of incompressible flow networks with arbitrary configuration having nodal sources and sinks as well as branch transducers can be determined. In contrast with the conventional steady-state network analysis methods, the new technique can be extended to …

A Color Photometer For Calibrating Light Sources, Harvey Gartner

Theses

A Color Photometer designed to calibrate tungsten sources to a standard source has been produced. It is accurate to within a few mired values, though not enough testing was done to specify its limits. There is also a good probability that the color -photometer can be used to find the color temperature of most tungsten sources including many that are not close to the color temperature of the standard source .

Determining The Temperature Of Hot Solid Bodies By Means Of Photographic Pyrometry, Using The Two-Filter Comparison Method, Edward White

Theses

At means of determining the temperature of a hot solid body by photographic means has been developed. For the purposes of this experiment, a General Electric tungsten ribbon filament lamp, with an operating range of 12 to 18 amperes was used as the object. From published curves, it was found that the color temperature of the filament varied from 2220K to 2990K over the above amperage range. It is therefore possible to vary the color temperature with a powerstat and to monitor it with an ammeter. Using two front surfaced mirrors, the lamp illuminated both sides of a photometric edge …

Theory Of Optical Spatial Filtering And Its Application To Enhance Low Contrast Fingerprint Images, Ludwig Scherlowski

Theses

Image improvement, through the use of the Fourier transform property of lenses using various frequency blocking filters, was investigated to determine possible utilization of this technique to enhance low contrast fingerprint image characteristics. Ten basic fingerprint patterns were degraded in contrast and then used as the object t(x,y) in an optical spatial filtering setup. A series of frequency blocking filters were used in an effort to improve the degraded object image. Visual comparison of the filtered images obtained by using a double band frequency blocking filter, which produced the most satisfactory images, shows improved overall contrast. Random ridge enhancement was …

An Instrument For Rapid Determination Of Granularity In Photographic Film Samples, Melvin E. Pollard

Theses

A scanner based on the principle of the classic microdensitometer was assembled for the purpose of rapid granularity determination. A rotary stage was used to allow the generation of a root-mean-square (rms) voltage signal proportional to rms Transmittance in the sample. A mathematical relation was then developed to calculate granularity. The scanner was calibrated and was proved capable of 10 percent accuracy with 95 percent confidence.

Development Of An Apparatus To Obtain Temperature Profiles Of Molten Flowing Polymers, Ismail Kemal Saltuk

Theses

The object of this investigation is to develop and test an apparatus to predict temperature profiles of polymer melts in laminar flow in a heat exchanger, with non-isothermal wall conditions.

A commercial polyethylene melt is pumped at various flow rates through a smooth 0.957 in. I.D. pipe. The entrance temperature of polymer is maintained uniform.

Radially distributed six thermocouples (0.062 in. 0.D.) are placed at 2.5 ft. intervals from the entrance of heat exchanger. Immersion of these probes parallel to the flow direction, reduced the errors due to the conduction of heat from the tube wall to the thermocouple stems. …

Aiir Pollution Emissions From Turbine Powered Aircraft, Raymond Arthur Filippini

Theses

The major pollutants that are emitted by jet aircraft include: particulate matter (soot), carbon monoxide, aldehydes, hydrocarbons, and nitrogen oxides. The first of the pollutants, particulate matter (smoke), constitutes not only a visual nuisance but is also a potential health problem. The rest, which are not visible, are irritants and in high enough concentrations can be toxic.

Since pollutants emitted by jet aircraft are of the same type as those given off by a car, a direct comparison is possible. In one landing take off cycle (LTO), a four engine jet aircraft emits the same amount of particulate matter as …

Phosphate Removal From Sewage Using A Combination Of Ferric Chloride And A Polymeric Flocculant, Ravindra C. Patel

Theses

The present work is concerned with a newer technique and approach to the problem of phosphate removal from waste water. This includes the removal of phosphate from the sample of activated sludge, i.e., a sample from the aeration tank of the secondary sewage treatment. The phosphate is removed by using ferric chloride as a precipitating agent and a cationic polyelectrolyte (P.E.) as a flocculating agent. Results of this study showed that: (a) P.E. addition gives a significant improvement in phosphate removal over that obtained by ferric chloride alone. In some cases the phosphate removal increased from 92 to 96.5 per …
