"Effectiveness of online recruitment system : evidence from augere wireless broadband Bangladesh limited (QUBEE)"
(BRAC University, 2014-09) Haque, Nusrat; Jabir Al Mursalin
Augere was established in September 2007 by an experienced team of global telecoms executives with the vision of delivering 'broadband for all'. Augere's first commercial network launched in Pakistan in July 2009 and was closely followed by the Bangladesh network in October 2009 under the brand name QUBEE. Working as a HR Executive for QUBEE, I have enriched my knowledge and skills and have got the opportunity to submit a report on “Effectiveness of Online Recruitment System: Evidence from Augere Wireless Broadband Bangladesh Limited” as assigned by my academic supervisor during my internship period. The purpose of a hiring event is to reach out to prospective employees and bring the specific kind of skills and experiences in the organization especially those which cannot be built from within. For external recruitment QUBEE posts job advertisement in the BDJOBS website and recruits the best possible candidate from the pool of applicants who applied for the position. BDJOBS online recruitment system can shortlist the application forms according to years of experience, skills, and educational attainment relevant to the job vacancy. Besides this, QUBEE also offers the contractual employees a chance to face the interview if their qualification and job match is similar to the position applied. Also other external referral candidates may apply through employees of our company. In such cases, the line managers send the resumes to the HR department for shortlisting. Then channels of interview are conducted before making the final selection. This report makes a comparison of BDJOBS online recruitment system with the internal recruitment system of QUBEE. The effectiveness of online job recruitment system is based on Performance, Reliability, Security and Cost-effectiveness. Speaking about the performance of BDJOBS software, it could facilitate efficient filtering of qualified candidates and could provide a well-matched shortlist of qualified applicants compared to the manual process of Internal Recruitment. In terms of Reliability, BDJOBS system could produce the required results with precision and could filter out applicants’ forms without anomalies and any form of discrimination while internal recruitment also provides correct results but with more expenditure of time and effort. BDJOBS had the mechanism to protect and control programs and data, and it provided its users passwords as security against unauthorized users while the internal recruitment system of QUBEE is not capable to control any kind of mechanism. Recruitment through BDJOBS requires certain amount money to be paid for each job posting no matter the desired candidates has been hired or not. Lastly, it can be said that online recruitment is more efficient compared to internal recruitment. Online Recruitment is capable of reaching potential employees at a shorter span of time. It is recommended that QUBEE should develop online recruitment system through their own web portal which is more cost effective and also it can build our own talent pool to source for future job opportunities.
Impact of Quantum Mechanical Correction in Surface Potential Based Compact Model on the Drain Current of Nanoscale MOSFETs”

Impact of the Quantum Mechanical (QM) correction in surface potential based compact model on the drain current of nanoscale MOSFETs is studied. We have considered a QM correction model to the surface potential (l/ls) based compact model of M. A. Karim and A. Haque which has been proposed recently. This model does not use the bandgap widening approach. It directly adds the correction term to the semiclassicall/ls. It accounts for the wave function penetration effect into the gate dielectric. The validity of this model has been demonstrated through the modeling of the gate C - V characteristics. In our work we have studied the effect of this correction on the drain current characteristics of nanoscale MOSFETs. The results have been compared with two other models, PSP and Pregaldiny et al. both these methods incorporate QM correction through the bandgap widening approach. QM correction to l/ls in PSP is derived from triangular well approximation while Pregaldiny uses the variational approach. When the wave function penetration effect is considered for a given semiconductor charge density the average distance of charges from the Si-gate oxide interface considering the QM effect is reduced. This leads to the lowering of l/ls also. So the models neglecting the wave function penetration effect tend to overestimate the l/ls. Hence both PSP and Pregaldiny which overestimate l/ls tend to underestimate the drain current. The Karim model shows higher current than the two existing models and predicts a lower, more accurate threshold voltage. The percentage deviation of the drain current of the QM corrections of the PSP and Pregaldiny models has been observed with respect to Karim model. The percentage deviation is around 10 - 50% at higher gate voltage but the situation is extreme around 80 - 90% in moderate inversion (VGS ~ VT ) whose effect is more pronounced. Comparison between them shows that the wave function penetration effect into the gate dielectric plays an important role in modeling the drain current of nanoscale MOSFETs.
