Abstract Attrition and paroxysm of highly inflammable petroleum products in storage tanks, pipelines and/or haulage trucks is increasingly becoming a scourging socio-environmental quandary with a detrimental effect on the Nigerian economy. Non availability of a holistic response time analytic master plan is a major enigma while industrial disaster managers perhaps are the major culprits since they are mostly not time cognizant for spry and pragmatic delivery of service. The aim of this exposition is to ruminatively carry out cerebral chronological corollary perusal for blitzing fire paroxysms and pipeline attrition in Nigeria on Microsoft excel spread sheet. Comprehensive data validation was done for all models by substituting all solutions of matrix into the predicted time response model. Results of predicted time response model in minutes for case A gave; 101x1 + 79x2 + 59x3 + 45x4 + 24x5 = 358. The predicted time response model for case B gave 78x1 + 56x2 + 43x3 + 30x4 + 13x5 = 260. The predicted time response model for case C gave; 74x1 + 56x2 + 42x3 + 29x4 + 10x5 = 252. Results of these models shows that the average cumulative response time dropped from 3.58 minutes to 2.52 minutes from case A to case C while the coefficients all reduced in their values from model A to C. Improving the source of data gathering and computational processes is recommended for enhancement of this study.

Advances in network technology have encouraged the development of ad-hoc services. MANET is one of them. In MANET, a routing protocol is required that can facilitate communication reliably. To get this reliable routing, in this study simulation of two routing protocols, namely AODV and OLSR. In the Manhattan Grid Mobility (MGM) model with communication loads using the FTP protocol. The simulation results show that the end-to-end value of service quality is 0.00210 second and throughput of 0.353428 Mbps for high FTP load in AODV routing. While the OLSR protocol routing obtained end to end delay value is 0.00071 second and throughput of 0.532025 Mbps for high load load FTP. For high load FTP traffic loads, 0.042436 second response time upload and 0.085789 second time response download on AODV protocol routing. On the OLSR routing protocol the upload time response rate is 0.084756 second response time and 0.09271 seconds download time response.

The study examined the effects of information load and syntax in user-initiated text formatting commands on the performance of computer-naive operators. Information load was varied through the number of parameters following the command and the number of alternatives for each parameter. Parameter values were specified using two types of syntax: mnemonic words and sequential numbers. Measures of operator response time and accurracy were taken on tests of command specification and command interpretation. Increases in the number of command parameters and number of alternatives per parameter contributed equally to increases in response time. Response time for word syntax was slower than numeric syntax. Performance improvements over tests were greater for word syntax than numeric syntax. The findings were interpreted as indicating the importance of the association value of words used in software languages which use English words.

Objective: To examine the performance differences on the Test of Variables of Attention (TOVA) among different IQ level groups. Method: The present study examined the results of the TOVA with 138 elementary students aged 6 to 10 years who were assigned to one of four different groups based on their scores from the Wechsler Nonverbal Scale of Ability (WNV; low average: IQ < 90, average: IQ between 90 and 109, high average: IQ between 110 and 119, superior: IQ between 120 and 129, and very superior: IQ > 129). The latter two groups were combined. Results: On all TOVA measures (response time, response time variability, errors of omission and commission, and ADHD scores), intellectual functioning significantly influenced performance. Conclusion: The results of the present study indicate that performance on the TOVA was affected by intellectual functioning.

The role of IoT gateway on IoT network is vital, like for strengthen the sensor management. Accordingly, in this research designed an IoT gateway based on MQTT Protocol which implemented in Intel Edison platform and using ten node sensors with star topology.Results from this research is an IoT gateway system who capable to receive data packet from node sensor, saves the data in database, and publishes the data to MQTT broker. User able to do data acquisition by subscribe method, using MQTT Dasboard application. The system tested by doing the calculation of time response of gateway with variation of data length and variation of distance, life time of node sensor testing by the variation of data length. The conclusions are the time average of from data acquisition by node sensor until gateway saves the data in database and user subscribes the data is twelve seconds. The shorter the data length makes the response time of gateway faster and makes the life time of node sensor shorter because the measured current is bigger. The distance is not gives any impact to the response time of gateway.

To solve the problems of long-time response and data redundancy in EPG obtaining of current interactive TV Portal, a new Portal system towards interactive TV terminals is designed and accomplished based on Ajax technology and jQuery frame. This system realizes asynchronous and cross-domain transfer of page information in batches, which also lays the foundation of real-time refresh of the page. Project results suggest that response time is shortened and resources are efficiently utilized while displaying and playing functions are ensured.

Objective: The purpose of this study was to verify changes in a driver’s emotions through the physical characteristics of haptic signals. This is to improve the performance of drivers by designing haptic signals with emotional semantics. Background: Currently, drivers receive a variety of information through intelligent systems installed in their vehicles. Because this is mainly achieved through visual and auditory channels, an excessive amount of information is provided to drivers, which increases the amount of information and cognitive load that they must accept. This, in turn, can reduce driving safety. It is, therefore, necessary to develop a haptic signal, a sensory channel that has not been widely used in in-vehicle information systems. Methods: The experiment was performed to collect a driver’s emotions according to the haptic signal in a driving simulator. Haptic signals were designed by various frequencies and accelerations, and driver emotions were collected through Kansei engineering techniques and analyzed through factor analysis. To verify intelligibility, haptic signals were compared and evaluated based on response time, response rate, and amount of transmitted information. Results: The final determined emotional map consisted of dangerousness and urgency. Based on the emotional map, four emotional semantic haptic signals were designed. It was confirmed that these four signals displayed higher performance than the discriminability haptic signal in terms of response time, response rate, and amount of transmitted information. Conclusions: Using emotional maps, it is possible to design haptic signals that can be applied to various driving situations. These maps may also assist in securing design guidelines for haptic signals that apply to in-vehicle information systems.
