In digital photography, the RGBE filter is an alternative color filter array to the Bayer filter (GRGB). It similarly uses a mosaic of pixel filters, of red, green, blue and “emerald” (“like cyan” according to Sony), and so also requires … Continue reading →

A filter specifies which transactions to collect data from. Sampling specifies what subset percentage or number of transactions to collect data from. Filters and sampling work at the root (or edge) transaction level. What is filtering of data means? Data … Continue reading →

Image sensors built into today’s digital cameras and mobile phones mostly use either the CCD (charge coupled device) or CMOS technology. Both CCD and CMOS are semiconductor devices that serve as “electronic eyes.” While they both use photodiodes, they differ … Continue reading →

Like IMAX, Cinemark XD is also a popular movie format. XD. stands for “Extreme Digital Cinema”, while IMAX stands for “Image Maximum”. Cinemark has emerged with improved audio-visual systems and enhanced seating. Cinemark has the same screen size and resolution … Continue reading →

CCDs are the most frequently used image detectors as they have many advantages, including larger dynamic range, good quantum efficiency, low noise, linear response, and negligible geometrical distortion. CCD cameras are extensively used because of their low-light image capturing ability. … Continue reading →

Samsung’s latest super-sized camera sensor is the “Isocell HP1.” It has a whopping 200 MP sensor, making it the highest-resolution smartphone camera sensor ever made. If you saved an image from it at full resolution, you’d end up with something … Continue reading →

If you want, you can convert a RAW image to any other format for editing. Besides that, if you want to screen your photos, then DNG would be a better option. This is because RAW files might not be directly … Continue reading →

Connect your supported phone to Wi-Fi or a cellular network. Go to the Settings menu on your phone and select Alexa. Turn Alexa Hands-Free ON and follow the on-screen instructions to complete setup. Can I use my phone as an … Continue reading →

Download the Alexa App Open the app store on your mobile device. Search for Amazon Alexa app. Select Install. Select Open and sign in with your Amazon Account. Install Alexa widgets (optional). Why won’t my Alexa app open? Alexa app … Continue reading →

Lead batteries are the lowest cost option compared with other battery technologies, in terms of both upfront cost and over the lifetime of the system. An initial investment in batteries at a renewable energy facility is $150-$200/kWh compared to other … Continue reading →

Solar and wind facilities use the energy stored in lead batteries to reduce power fluctuations and increase reliability to deliver on-demand power. Can solar power be stored? Solar energy can also be stored in electrochemical batteries. When solar energy is … Continue reading →

This usually ranges from 85% to 95%, with 90% being about average. When running such things as motors, the efficiency actually has two parts to it – the efficiency of the inverter, and the efficiency of the waveform. What is … Continue reading →

Store it in a home battery, and discharge it whenever your solar panel generation tapers off. This is what it means to have true energy security and independence. Home batteries are the only way to go off-grid without making huge … Continue reading →

Use the smallest inverter possible for the load. Larger inverters are less efficient on small loads and will use more on standby. The most efficient way to charger the laptop is a dc-dc power cord, no inverter. Do bigger inverters … Continue reading →

Because nuclear power plants are not designed to ramp up or down, their generation is constant at all times of the day. When demand for electricity is low at night, pumped hydro facilities store excess electricity for later use during … Continue reading →
