Compositional Zero-Shot Learning (CZSL) has emerged as an essential paradigm in machine learning, aiming to overcome the constraints of traditional zero-shot learning by incorporating compositional thinking into its method-ology. Conventional zero-shot learning has difficulty managing unfamiliar combinations of seen and unseen classes because it depends on pre-defined class embeddings. In contrast, Compositional Zero-Shot Learning leverages the inherent hierarchies and structural connections among classes, creating new class representations by combining at-tributes, components, or other semantic elements. In our paper, we propose a novel framework that for the first time combines the Modern Hopfield Network with a Mixture of Experts (HOPE) to classify the compositions of previously unseen objects. Specifically, the Modern Hopfield Network creates a memory that stores label prototypes and identifies relevant labels for a given input image. Subsequently, the Mixture of Expert models integrates the image with the appropriate prototype to produce the final composition classi-fication. Our approach achieves SOTA performance on sev-eral benchmarks, including MIT-States and UT-Zappos. We also examine how each component contributes to improved generalization.

Lithium sulfur (Li-S) batteries have become one of the promising rechargeable storage devices due to its abundancy, low cost, non-toxicity, environmental friendliness and high theoretical specific capacity. However, the insulating nature of sulfur and the shuttling effect of polysulfides have limited their applications. In order to alleviate these problems and make Li-S batteries more promising, we have synthesized a composite of reduced graphene oxide and sulfur (rGO-S) as electrode material for these batteries. In this paper, graphite oxide was prepared from graphite powder by Improved Hummer’s method followed by ultrasonic exfoliation to make Graphene Oxide (GO). The GO suspension was hydrothermally reduced and heated in a hot air oven at 150 °C for 4 hours followed by the addition of sulfur (S) in a ratio of 0.1:1 and 1:1 by mass and heated again at 180 °C for another 4 hours to make a composite of rGO-S. The electrode of the rGO-S composite was prepared by making a slurry of active material, carbon black and polyvinylidene fluoride (PVDF). The sample of GO and rGO were analyzed using Ultraviolet (UV)-Visible and Fourier Transform Infrared (FTIR) spectroscopy. The composite material was analyzed using X-Rays Powder Diffraction (XRD) while the energy density and charge discharge curves of the electrode were analyzed using cyclic voltammetry (CV).

The performance of lube oil condition with both natural gas and biogas as fuel has been investigated for a Genset having 1 mega-watt capacity. The algorithm based oil change intervals between 30-1042 hours and 30-300 hours; following a normal distribution, were employed for natural gas and biogas respectively. Test samples after full load operation were collected for laboratory analysis. The results show that there is accelerated lube oil dilution with biogas and oil change interval is one third of natural gas. Significant sulfur deposits on inner cylinder surface with natural gas were observed. Total base number (T.B.N), kinematic viscosity, oxidation and iron debris in lube oil followed similar trends. However, nitration and copper debris showed different patterns for natural gas and biogas during condition monitoring of lube oil.

The expansion of the university education is now a reality of Albanian society. The quality of this expansion is far from what is required by academic staff and what is expected from the society. Regarding school leadership, it is seen to be of great interest during the first years of the twenty-first century, due to the fact that it is widely believed that leadership qualities bring about significant change in schools and student’s’ results.(Bush, 2009). In order to have a more effective and fair education the current system of higher education requires further improvement. It should satisfy the increase of student interest in achieving high scores and decide the right balance between the student’s’ scores and the financial support to attend the college. The motivation of students in achieving high scores should start from high school and should be followed by their right to choose for themselves university education based on their university grant won according to the ranking of their ‘A’ level results. Successful completion of ‘A’ levels is followed by the amount of the winning grant by the candidate and the candidate decides where he/she will use it. This motivates the high school students in achieving high scores and the students themselves are oriented according to the standards, quality of service and the reputation that the university offers. The universities are more competitive and their staff will be more motivated to offer their best to the students. The society would benefit people of better quality , the proper elite, as a result of versatile work by all the intellectual staff. DOI: 10.5901/jesr.2014.v4n3p157
