Aksesibilitas adalah desain sebuah bangunan yang menjamin keamanan dan mudah dijangkau oleh semua orang dan tidak terkecuali, termasuk individu dengan disabilitas. Salah satu bentuk aksesibilitas adalah adanya guiding block atau ubin tekstur pemandu yang menjadi penunjuk jalan bagi pejalan kaki tunaneta di tempat umum. Akan tetapi guilding block yang sudah ada terkadang membuat penyadang tuna netra mengalami kecelakaan seperti tertabrak pot atapun tiang listrik. Pada saat ini, alat untuk membantu penyandang tuna netra untuk melakukan aktivitas hanyalah sebuah tongkat yang memiliki panjang 120 cm, Tongkat tersebut memiliki keterbatasan seperti jangkauan alat, tidak dapat mendeteksi berbagai object di sekeliling penyandang dalam waktu yang cepat. Pada penelitian ini akan dibuat sebuah alat berupa sarung tangan untuk membantu dan meringankan aktivitas seperti mengetahui object yang berada di depan para penyandang tuna netra tersebut. Dengan bantuan sensor ultrasonic kemudian di proses menggunakan Arduino nano. Dengan keluaran menghasilkan getaran dan suara yang berasal dari motor dc dan buzzer. Dapat memberitahukan seberapa dekat objek. Hasil pengujian yang dilakukan sebanyak sepuluh kali dalam hal jarak dan delay pada tiga kondisi. Sarung tangan memiliki error yang kecil dalam hal pengukuran jarak tetapi memiliki error rate yang tinggi di setiap object. . Kemudian pada pengujian delay didapatkan perbedaan nilai yang sedikit pada object yang berbeda dan pada jarak tertentu dari satu hingga tiga meter didalam tiga kondisi.

Purpose This retrospective analysis examined group differences in error rate across 4 contextual variables (clusters vs. singletons, syllable position, number of syllables, and articulatory phonetic features) in adults with apraxia of speech (AOS) and adults with aphasia only. Group differences in the distribution of error type across contextual variables were also examined. Method Ten individuals with acquired AOS and aphasia and 11 individuals with aphasia participated in this study. In the context of a 2-group experimental design, the influence of 4 contextual variables on error rate and error type distribution was examined via repetition of 29 multisyllabic words. Error rates were analyzed using Bayesian methods, whereas distribution of error type was examined via descriptive statistics. Results There were 4 findings of robust differences between the 2 groups. These differences were found for syllable position, number of syllables, manner of articulation, and voicing. Group differences were less robust for clusters versus singletons and place of articulation. Results of error type distribution show a high proportion of distortion and substitution errors in speakers with AOS and a high proportion of substitution and omission errors in speakers with aphasia. Conclusion Findings add to the continued effort to improve the understanding and assessment of AOS and aphasia. Several contextual variables more consistently influenced breakdown in participants with AOS compared to participants with aphasia and should be considered during the diagnostic process.

Abstract. When concentration tests are completed repeatedly, reaction time and error rate decrease considerably, but the underlying ability does not improve. In order to overcome this validity problem this study aimed to test if the practice effect between tests and within tests can be useful in determining whether persons have already completed this test. The power law of practice postulates that practice effects are greater in unpracticed than in practiced persons. Two experiments were carried out in which the participants completed the same tests at the beginning and at the end of two test sessions set about 3 days apart. In both experiments, the logistic regression could indeed classify persons according to previous practice through the practice effect between the tests at the beginning and at the end of the session, and, less well but still significantly, through the practice effect within the first test of the session. Further analyses showed that the practice effects correlated more highly with the initial performance than was to be expected for mathematical reasons; typically persons with long reaction times have larger practice effects. Thus, small practice effects alone do not allow one to conclude that a person has worked on the test before.

This report describes an evaluation of »observer variation« in history taking and examination of patients with abdominal pain. After an initial survey in which the degree of observer variation amongst the present authors fully confirmed previous rather gloomy forecasts, a system of »agreed definitions« was produced, and further studies showed a rapid and considerable fall in the degree of observer variation between the data recorded by the same authors. Finally, experience with a computer-based diagnostic system using the same system of agreed definitions showed the maximum diagnostic error rate due to faulty acquisition of data to be low (4.7°/o in a series of 552 cases). It is suggested as a result of these studies that — at least in respect of abdominal pain — errors in data acquisition by the clinician need not be the prime cause of faulty diagnoses.

Customer satisfaction is influenced by service quality factors, this study aims to find out and analyze how much influence the quality of service on customer satisfaction is felt by customers who use the service of Poor Rice (Raskin) at the Office of Public Companies Logistics Agency (Perum BULOG) in Sampit City Regency East Kotawaringin. The research method used in this study is the method of observation, questionnaire/questionnaire and documentation using a Likert scale and the method of determining the sample used is the error rate of 5% as many as 213 samples. Testing the hypothesis used is a statistical test with the formula "Product moment person". The results showed that there was a very strong correlation between Service Quality and Customer Satisfaction of the Office of Public Company of the Logistics Affairs Agency (Perum BULOG) in the District of East Kotawaringin. As much as 0.9968514278 based on the calculation of Pearson Product Moment value.

The problem of classification of the realisation of the stationary univariate Gaussian random field into one of two populations with different means and different factorised covariance matrices is considered. In such a case optimal classification rule in the sense of minimum probability of misclassification is associated with non-linear (quadratic) discriminant function. Unknown means and the covariance matrices of the feature vector components are estimated from spatially correlated training samples using the maximum likelihood approach and assuming spatial correlations to be known. Explicit formula of Bayes error rate and the first-order asymptotic expansion of the expected error rate associated with quadratic plug-in discriminant function are presented. A set of numerical calculations for the spherical spatial correlation function is performed and two different spatial sampling designs are compared.
