The Past Present and Future of Technology Inventory Control Essay

The Past Present and Future of Technology Inventory Control - Essay Example Technology evolved to the second generation, which included electronic computers for scientific and numerical calculations. These computers were now convenient, reliable and could store much information. Standard packages emerged for inventory control applications, making it easy to sort, analyze, and process data. The result was reduction in prices of goods and services leading to increased transactions and hence demanding more efficient and faster equipment. The third generation was online network databases that enabled online transaction processing (Gray 4). This era enabled a person to run many concurrent transactions and many users shared one database. Many programs developed in this era are still useful today in inventory control (Chief Supply Chain Officer Insights 13). The fourth generation inventory control devices were relational databases that enabled data definition, data navigation, and data manipulation (Gray 5). It enabled the capturing of inputs and outputs of merchandise to the user device. The programs in this generation are convenient even in today’s life for client server computing. The devices that followed emerged in the year 1995 and were multimedia databases that still exist in today’s life (Gray 6). In complex objects, the database made it possible to search, compare, and manipulate the data. This database could store and retrieve information and it made inventory control easy by adding on time and time interval data types. In the present, computer hardware has enabled the evolution of inventory control from manual and paper based processing to information search engines. The inventory control devices used in the present include barcode scanners to read every barcode in every item, mobile computers to capture data like the batch numbers and the inventory software for tracking the inventory sales

Fully discuss absortion and emission spectroscopy follows instruction below - Assignment Example The atomic emission spectrometer consists of four major components. These include the atomizer, the nebulizer, the Monchromator and the detector. Flame is used to atomize the sample so that the resultant atoms can interact with the radiation. Monchromator is used to discriminate wavelengths that do not conform to the requirements of the experiment. Detector is used to detect the emitted wavelengths. During experiment, five processes take place. The first three processes takes place simultaneously. These threes processes include the dissolvation, vaporization and atomization. They take place when the sample is introduced into the atomizer. Dissolvation is the process where the solvent sued to dissolve the sample is evaporated (Crouch & Skoog 63). The thermal heat energy from the atomizer forces the solvent, which is water, to evaporate instantly. Vaporization occurs when the resultant solid sample is vaporized into gases. Lastly, the atomization occurs when the resultant gases are broken down into atoms. All these takes place as a result of high thermal energy from the flame. Principally, both the atomic emission spectroscopy and the atomic absorption spectroscopy exhibit all these three steps. However, the fourth step is what differentiates the atomic emission spectroscopy from the atomic absorption spectroscopy. I atomic emission spectroscopy, the gaseous products obtained are excited to higher energy level. Excitation occurs when the electrons in the atoms gain energy and move to higher energy levels. However, the electrons cannot stay in the higher energy level indefinitely (Crouch & Skoog 71). This is because there is no constant energy to maintain them in the higher energy levels. Because of this, they are unstable. Consequently, to regain their stability, electrons would be forced to drop back to their original state called ground state. This process is called de-excitation. De-excitation is normally accompanied by several
