Most research works nowadays deal with real-time Internetof Things (IoT) data. However, with exponential data volume increases,organizations need help storing such humongous amounts of IoT data incloud storage systems. Moreover, such systems create security issues whileefficiently using IoT and Cloud Computing technologies. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) has the potential to make IoT datamore secure and reliable in various cloud storage services. Cloud-assisted IoTssuffer from two privacy issues: access policies (public) and super polynomialdecryption times (attributed mainly to complex access structures). We havedeveloped a CP-ABE scheme in alignment with a Hidden HierarchyCiphertext-Policy Attribute-Based Encryption (HH-CP-ABE) access structure embedded within two policies, i.e., public policy and sensitive *** this proposed scheme, information is only revealed when the user’sinformation is satisfactory to the public policy. Furthermore, the proposedscheme applies to resource-constrained devices already contracted tasks totrusted servers (especially encryption/decryption/searching). Implementingthe method and keywords search resulted in higher access policy privacy andincreased security. The new scheme introduces superior storage in comparisonto existing systems (CP-ABE, H-CP-ABE), while also decreasing storage costsin HH-CP-ABE. Furthermore, a reduction in time for key generation canalso be ***, the scheme proved secure, even in handling IoT datathreats in the Decisional Bilinear Diffie-Hellman (DBDH) case.

Impact Assessment of Incentive Schemes for the Sustainable Development of Nigerian Construction Industry

Journal of Civil Engineering and Architecture 2012年第9期6卷 1194-1201页

The concept of construction productivity and the needs for incentive schemes towards improving the performance of Artisan has long been established. The choice of particular scheme either financial or non financial and to what level it contributes to the productivity of employees remain at stake. Therefore, this study set to evaluate the level of awareness, impact and contribution of the schemes with more emphasis to the non financial incentive schemes. A questionnaire survey involving management and artisans of the three tiers of NCl （Nigerian Construction Industry）： large, medium and small within Kaduna and Abuja Nigeria was conducted. Three hundred （300） responses from the management and artisans were used for analysis, inferences and conclusions. The survey result revealed that non-financial incentive schemes are mostly employed in the large and medium scale construction firms. Though, preference by medium and small scale firms was based on those that do not require fund to implement and maintain. It was concluded that, construction firms operating in Nigeria ought to strive more towards implementing non-financial incentive in their organization since artisans are willing to improve their output.

Evaluation of Low Saline “Smart Water” Enhanced Oil Recovery in Light Oil Reservoirs

引用

World Journal of Engineering and Technology 2014年第1期2卷 13-22页

With the depletion of natural driving forces responsible for pushing the oil from reservoirs & declination of oil recovery after secondary stage, the emphasis is now on EOR techniques. The low saline flooding is a type of EOR which gains the attention of researchers due to its easiness to use implications, less cost & environment-friendly nature. Though the low salinity effect has been seen in various labscale core flooding experiments as well as field pilot projects, the mechanism which actually leads to this enhancement in recovery is still the area of research among researchers which is wide open and needs to gain consensus. Seeing the wide mechanisms taking place under different scenarios, it is certain that more than one mechanism is actually supplementing each other in reducing the residual oil saturation while LSW flooding. This study has been undertaken investigations on the low saline flooding in unconsolidated Ottawa sandpack cores with two different, Weyburn & Pelican crude oil, to find out the optimum salinity, LSW Slug Size & underlying mechanisms during LSW flooding. Several core flooding experiments were performed under secondary as well as tertiary recovery stage by unsteady state method. With the reduction of brine salinity from 5000 PPM to 1500 PPM, the oil recovery increased in secondary stage & decreased further upon reduction in salinity to 500 PPM gaining the peak at 1500 PPM. Small enhancement in tertiary recovery of 2.24% observed upon switching to 1500 NaCl PPM brine after injection of formation brine in secondary stage for Weyburn Oil, though large tertiary recoveries of the order of 9.95% for effective oil viscosity of 4 cP and 7.32% for 29.7 cP were observed for n-dodecane diluted Pelican Oil. LSW slug size of 25% pore volume was found to be effective in producing Weyburn Oil in secondary stage.

Investigating Improved Oil Recovery in Heavy Oil Reservoirs

引用

World Journal of Engineering and Technology 2014年第1期2卷 23-31页

作者： Yogesh Kumar Suman Ezeddin Shirif Hussameldin ibrahim abdulsalam ala-Ktiwi Faculty of Engineering University of Regina Regina Canada Faculty of Engineering University of Tripoli Tripoli Libya

Primary production mechanisms do not recover an appreciable fraction of the hydrocarbon initially in place (HIIP). Practical knowledge has shown that, at the point when the natural energy in a heavy oil reservoir is nearly or altogether depleted, the recovery factor does not exceed about 20%. Some heavy oil reservoirs do not produce at all by natural drive mechanisms. This often necessitates adopting a production improvement strategy to augment recovery. Prior to implementing an improved oil recovery method (either secondary or tertiary) in the field, it is very important to investigate its potential for success. Reservoir simulation is a part of a continuous learning process used to gain insight into the feasibility and applicability of improved oil recovery methods. In this project, GEM compositional reservoir simulator has been used to study the efficiencies of different improved oil recovery strategies, ranging from waterflooding to solvent injection. The drainage volume investigated is a hypothetical box-shaped heavy oil reservoir composed of three distinct permeable layers.

Objective:To determine if there was any difference in SpO2 readings during exchange blood transfusion(EBT).Methods:A prospective cross-sectional study of neonates with severe neonatal jaundice requiring EBT was *** saturation was recorded before,immediately and 15 minutes after EBT by using a pulse ***:This study included 30 neonates with 20 males and 10 *** age ranged from 1 to 12 days with a mean of(5.4±2.9)***-EBT SpO2 ranged from 90%to 98%with a mean value of(94.3±2.2)%;SpO2 in the end of EBT ranged from 85%to 99%with a mean value of(94.1±3.2)%;SpO2 at 15 minutes after EBT ranged from 77%to 99%with a mean value of(94.8±4.1)%.There was no significant difference between SpO2 values at onset of EBT and either immediately or 15 minutes after EBT(P=0.770 and 0.422,respectively).SpO2 showed no significant difference between neonates who were infused with blood of different storage times(0.999)and 15 minutes after EBT(P=0.887).Besides,SpO2 values were compariable in neonates with hematocrit<45%or≥45%at the onset of EBT(P=0.284),immediately(P=0.118)and 15 minutes after EBT(P=0.868).Conclusions:EBT does not affect SpO2 in neonates.
