Designing Air Intake Ducts for High Speed Flight

A proven duct flow model is used to examine the influence of the intake duct geometric and inlet flow parameters on the pressure recovery performance of intake ducts for high speed flight. The geometric parameters include: the inlet parallel pipe length, the diffuser cone angle, the length of the faired transition from the pipe to diffuser cone as well as the degree of the fairing. The inlet flow parameters examined are: the boundary layer momentum thickness, the velocity profile shape and the turbulence level. The inlet parameter values used simulate those following a normal shock wave — turbulent boundary layer interaction inside the intake duct, i.e. they simulate the conditions at the inlet to the diffuser of a supersonic intak

New Clarification About Observation Billing May Improve Care for Behavioral Health Patients

Emergency Physicians provide ongoing care to psychiatric patients beyond the confines of a standard emergency room visit.  Often, when we identify patients who need specialty psychiatric care, patients board in the emergency department awaiting acceptance and transfer to an outside facility.  Even in cases where it has taken multiple days to complete the transfer, it has been unclear how to properly obtain reimbursement for this care.  We discuss a new coding clarification that may provide a pathway to improve part of this situation

Pengajuan penyelesaian Sengketa antara Nasabah dengan Bank dalam rangka Mediasi Perbankan kepada pelaksana fungsi Mediasi Perbankan dapat dilakukan oleh Nasabah atau Perwakilan Nasabah apabila telah memenuhi persyaratan. b. Pengaduan Penyelesaian Sengketa disampaikan kepada Direktorat Investigasi dan Mediasi Perbankan, Bank Indonesia, Menara Radius Prawiro lantai 19, Jalan M.H Thamrin No. 2, Jakarta 10110 dengan tembusan kepada Bank yang bersangkutan. c. Proses Mediasi dilaksanakan setelah Nasabah atau Perwakilan Nasabah dan Bank menandatangani perjanjian Mediasi (Agreement to Mediate)

Risks for Peripheral Arterial Disease in the Elderly with Type 2 Diabetes Mellitus : Their Correlation with High Sensitivity C-reactive Protein and Ankle-brachial Index

The Indonesian elderly population has been projected to increase up to about four-fold inthree decades (1990-2020). As a consequence of this population trend, the increased prevalence ofdegenerative diseases would be inevitable; this would include the prevalence of peripheral arterialdisease.This study aims to identify the correlation of diverse risk factors, either traditional or nontraditional,with the ankle-brachial index scores, and the correlation of novel non-traditional riskfactor, e.i. high sensitive C-reactive protein with the prevalence of perioheral arterial disease in theelderly, age 60-80 years old, with type 2 diabetes mellitus.Among the 146 elderly patients with type 2 diabetes mellitus, and based on measurement ofthe ABI score, approximately 30.9% of them had PAD. Some traditional and non-traditional riskfactors having a significant correlation with the ankle-brachial index score, were age (r = -0.396, p <0.001 for right ABI; r = -0.509, p < 0.001 for left ABI), supine systolic blood pressure (r= -0.268, p =0.012 for right ABI; r = -0.267, p = 0.013 for left ABI), 2-hour post-prandial blood glucose (r= -0.252, p = 0.018 for right ABI), and hsCRP (r = -0.280, p = 0.011 for right ABI; r = -0.402, p <0.001 for left ABI); whereas other risk factors like obesity based on waist circumference and BMI,non-supine systolic blood pressure, fasting blood glucose, HbA1C, duration of diabetes, plasma lipidsdid not show statistically significant different odd ratios. After linear regression test for risk factorshaving significant correlations with ABI, age and hsCRP were found to influence the ABI scores.Based on a case-control study, risk factors which, to some extent, had statistically significant valuesas risk factors, include older age (? 70 years old; OR = 7.737 [CI = 2.515-23.805]; p < 0.001),relatively high supine diastolic blood pressure (? 90 mmHg; OR = 6.882 [CI = 0.789-60.060]; p =0.048), and high concentration of hsCRP (> 3 mg/L; OR = 4.420 [CI = 1.287-15.181]; p = 0.013).Among these statistically significant risk factors, after logistic regression test analysis, only the age ofthe patient appeared to have significant influence on the prevalence of PAD.In conclusion, this study demonstrates a negative correlation between hsCRP and ABI score;and high levels of hsCRP appeared to be a risk factor for PAD. The age of the patient, however,appeared to be the strongest risk factor for PAD

“Not All FRIENDs are Equal”: Friendship Classification for Defending against Social Engineering Attacks

Social engineering is a serious security threat to Online Social Networks (OSNs). Identity theft, impersonation, phishing, and deception are some of the social engineering-based attacks that exploit vulnerabilities of interpersonal relationships of online users. As a result, relationships in OSNs need to be thoroughly examined. In this vein, we propose a relationship categorization model to evaluate relationship strength based on graph-theoretic properties and social network analysis (SNA) methods. For example, in Facebook, users may be categorized into close-neighbors, distant-neighbors, celebrities (influential by admiration), authority (influential by power), and loners. Close-neighbors category will help identify a set of trustworthy actors while an actor of distant-neighbors category should not be trusted as much as the former. A celebrity category actor should be more accountable, while a loner category actor will probably be less accountable. This type of categorization will help users engage in proper cybersecurity behaviors to avoid social engineering-based attacks

Pengaruh Kepercayaan dan Risiko pada Minat Beli Belanja Online

The use of internet and e-commerce in Indonesia grows continuously. The Internet has changed the consumer behaviour in meeting their needs. Therefore, this study aimed to determine the effect of trust in online stores and perceived risk on consumer online purchase intention. This study involved 180 internet users as respondents who have visited online shopping sites in Indonesia. The results found that consumer trust in online stores have negative effect on perceived risk in buying online. Otherwise, the trust has positive effect on online purchase intention. However, this study proves there is no risk in buying interest referring them to shop online. Furthermore, this study found that trust level of female customers to online shopping sites is higher than male customer
