Islamic architecture is rich in decorative patterns. Mosques were constructed in the past as simple buildings for offering prayers five times a day. However, in subsequent periods, various features of ornamentation in the form of geometry and arabesque were applied to the surfaces of mosques to portray paradise symbolically. This research applied descriptive approaches to examine the surviving patterns of the Aga-Khan-awarded Bhong Mosque and categorized these patterns as geometric and arabesque. This categorization was achieved by photography, use of software for patterns, and conducting interviews with local elderly persons in the region. The geometric patterns were simple 6- and 8-point star patterns. several of the eartiest examples of rosette petals exhibited 8- and 10-point star patterns and were categorized by incorporating the geometric style and location of mosques. This research investigated different arabesque categories and inscription types and determined the aesthetic and cultural reasons for their placement on various surfaces. Frescoes had different types of flowers, fruits, and leaves, and a few of them belonged to the local region.

当前电网是世界上最复杂的工程系统之一,但它存在一些限制,包括高度集中的电力生产系统和缺乏适应日益增长的需求的灵活性。然而,随着世界人口的不断增长,对可持续和可靠能源系统的需求变得比以往任何时候都更加紧迫。智能电网(sG)提供了一个有前途的解决方案,利用创新技术,如可再生能源、储能和能源使用控制,提高电力分配的效率和可靠性。本研究提出了一个智能电网系统的模型和模拟设计,应用太阳能电池板(PV)、风力发电机和备用电池的组合,针对巴基斯坦俾路支省昆塔市进行设计。我们利用HOMER Grid等先进软件工具,基于巴基斯坦气象局获取的数据,预测未来该地区的负荷需求。本研究将车辆到电网(V2G)和电网到车辆(G2V)技术融入到智能电网系统中。在G2V连接期间,通过双向充电技术,电动汽车(EV)电池可以在低负荷需求时以低价存储电力,并在电网需求高时以高价出售电力。同样,在V2G连接期间,汽车电池是在峰值需求期间为电网提供电力的电源。此外,车辆到电网(V2G)技术还允许在汽车不使用时(例如停车时)向电网返还电力,提高了电网稳定性并使车主能够赚取收益。在我们提出的系统模型中,我们根据需求响应计划选择了一个基准情况,然后将其与其他两种情况进行比较,这两种情况可以平衡电网和消费者负荷需求。在情况1中,该系统包括水电、输电、配电、负载和储能,而在情况2中,智能电网系统包括水电(GEN)、可再生能源(PV、风力涡轮)、电池、车辆到电网/电网到车辆和负载(智能家居、办公楼)。与基准情况进行比较后,情况1的年度电费分解成本为36,349美元,而情况2的年度电费分解成本为11,467美元。在情况1中,没有年度碳排放(CO2)因为只包括水电,而在情况2中,每年的碳排放(CO2)较低,为81.6吨/年。我们的研究结果表明,智能电网技术具有巨大的潜力,并为能源管理部门提供更好的工具,以开发可持续且具有成本效益的能源系统。此外,这项研究与政府的目标一致,即实现小型分布式发电(DG)和全球目标,为巴基斯坦及其它国家打造更加可持续和环保的能源未来铺平了道路。
