Two experimental studies are reported that were intended to evaluate alternative man-computer communication techniques within the context of a computer-based image interpretation facility. The first experiment, comparing five different data entry procedures, indicated that, although a procedure requiring the interpreter to enter report data directly using a teletype keyboard resulted in the shortest overall throughput time, a procedure involving message composition by the image interpreter with subsequent transcription by a communicator minimizes the time spent by the interpreter in report generation and maximizes the time available for the detection and identification of targets on aerial imagery. The second experiment evaluating alternative word form-data entry format combinations, showed no differences among the six combinations studied.

Points Of View

This paper outlines a method for combining alternatives for each of the factors bearing on a design decision and rank ordering all possible configurations of alternatives. The method permits the rank orderings to be based on the judgments of a relatively large number of persons having diverse points of view and experience but concerned with a common design problem. This method was used to rank order a large number of alternative reporting techniques that might be utilized within a context of a computer-based tactical image interpretation facility for each of four man-computer communication tasks. Results from the application of this method were compared with a scaling of stimuli using Thurstone's law of categorical judgment technique and with the results of a related experimental study.

<p>The Sea Beach Cahaya is one of the rising beach attractions in Kendal Regency, Central Java. In general, the tourism object of The Sea Pantai Cahaya still does not use many computer systems in their daily lives. As with tourism ticket purchases and also entrance tickets, vehicles that still use ticket paper as proof of payment, it is often disrupted if it is still fussing with the queue conditions and questions by visitors. On the other hand, report data collection is still considered slow.</p><p>One way to overcome the above problems is to make a ticket payment system that is computerized using the SAW (Simple Additive Weighting) method, replace paper tickets with a card model and also use the network to shorten report generation.</p>

AbstractAccurate determination of sensitivity and directivity is important for any underwater acoustic transducer. In this work, an automatic measuring platform was designed and implemented for characterizing underwater acoustic transducers. The overall hardware setup includes a PXI (PCI Extensions for Instrumentation)-based data acquisition system, computer-based controller module, motion controller module, and LabVIEW-based automatic calibration program. The system performs a sequence of operations automatically and achieves synchronous control of transmission and acquisition of real-time acoustic signals as well as processing, recording, and report generation. This measurement platform can be utilized for characterizing any type of acoustic transducer for its receiving sensitivity, transmitting response, and directivity measurement as per IEC60565 standard. The measurement results for RESON TC4034 and RESON TC 2080 transducers are presented and the results show that the system is able to carry out accurate calibration and characterization of any underwater acoustic transducer. Sources of uncertainty for calibration are also presented with the confidence level of approximately 95%.

The Individual

This study investigated the effects of printed factual information and three augmentative communication techniques on attitudes of nondisabled individuals toward nonspeaking persons with physical disabilities. Employing a 3 (augmentative communication techniques) x 2 (presence/absence of information) factorial design, subjects viewed a videotape depicting a nonspeaking adult having a conversation with a normal-speaking individual. Subjects in Condition 1 viewed a tape depicting the nonspeaking individual using unaided communication techniques; Condition 2 subjects viewed the individual using an alphabet board; subjects in Condition 3 viewed the individual using a computer-based voice output communication aid (VOCA). A scale assessing attitudes toward nonspeaking persons, the Attitudes Toward Nonspeaking Persons Scale (ATNP), was developed and validated for purposes of this study and was employed as the dependent measure. Results revealed that subjects expressed more favorable attitudes when provided with the additional information concerning the nonspeaking individual. Attitude favorability also increased with the sophistication of the augmentative communication technique.

Business As Usual

We examined the efficacy of an afterschool multicomponent reading intervention for third- through fifth-grade students with reading difficulties. A total of 419 students were identified for participation based on a 90 standard score or below on a screening measure of the Test of Silent Reading Efficiency and Comprehension. Participating students were randomly assigned to a business as usual comparison condition or one of two reading treatments. All treatment students received 30 min of computer-based instruction plus 30 min of small-group tutoring for four to five times per week. No statistically significant reading comprehension posttest group differences were identified ( p > .05). The limitations of this study included high attrition and absenteeism. These findings extend those from a small sample of experimental studies examining afterschool reading interventions and provide initial evidence that more instruction, after school, may not yield the desired outcome of improved comprehension.

Reflectance Measurements

Shin oak is a deciduous shrub that forms dense stands of brush on sandy soils in rangeland areas of the Rolling and High Plains of Texas. Plant canopy reflectance measurements made on shin oak showed that it had both low visible (0.63- to 0.69-μm waveband) and nearinfrared (0.76- to 0.90-μm waveband) reflectance values, a characteristic generally not shared by associated plant species or mixtures of species. The low reflectance values of shin oak caused it to have dark-red, reddish-brown, or brown image tones on color-infrared photographic, videographic, and SPOT satellite images that made it distinguishable from associated vegetation and other land use features. The optimum time to remotely distinguish this noxious shrub is during the mature phenological stage from June to September. Computer-based image analyses of video and satellite images showed that shin oak populations could be quantified. This technique can permit “percent land area” estimates of shin oak on rangelands. The aerial imagery is useful for detecting shin oak on smaller rangeland areas, whereas the satellite imagery is applicable in mapping large areas of shin oak distribution.

Experimental Findings

Coating disbondment on pipelines is a common phenomenon that leads to exposure of the pipeline metal to ground water solutions, promoting a corrosive environment which is associated with stress corrosion cracking (SCC). This investigation aims to understand the corrosion behavior and rate of pipeline steel under coating disbondments of varying sizes based on field data and experimental studies. In the analysis of the field data, dig reports provided by a Canadian gas transportation company were analyzed for cases of anaerobic corrosion under tape coatings. The analyzed field data provided a correlation between the tape coating disbondment size and corrosion rate found under the coating. The experimental studies aimed to understand the field findings. The analyses were performed on X-65 pipeline steel coupons placed in a vertical coupon holder with a PMMA shielding. To imitate the variation in the disbondment size, the gap size between the metal coupons and the shielding was varied (2 mm, 5 mm, and 10 mm, and infinite). The general corrosion rates were obtained through weight loss calculations. The experimental results were compared and correlated with dig-report data from the field for a development of cathodic protection and pipeline mitigation strategies.
